COA

A COA (certificate of authenticity) is a document that accompanies a piece of artwork to verify its authenticity.

The COA is typically issued by the artist, the gallery, or the publisher and includes details like the edition number, the size of the edition, and the materials used. It serves as a guarantee of the work's authenticity and can be important for valuation and resale. A COA provides collectors with the assurance they need when investing in a piece of art, adding credibility and value to the artwork.

Inner Love

Internal and external reflections coalesce in a print by Tomás Sánchez.Cuban artist Tomás Sánchez paints surreal visions of utopia in mind-bending detail. The artworks embody his commitment to preserving what remains of the wilderness, and a personal relationship with meditation spanning five decades.Inner Love places its cross-legged subject on a mirage-like island, mirrored perfectly in the water that surrounds it. As with many of the artist's landscapes, the scene is inspired by verdant forests and tranquil rivers close to his studio in Costa Rica. For Sánchez, the artwork provides space for a moment of self-reflection."I believe that Inner Love is a painting that can transmit to others the same peace that it transmits to me and, today, it is invaluable to receive a bit of peace."The edition transforms a larger painting into a fine-tuned UV pigment print complete with a silkscreen varnish seal. Printmakers paid particular attention to fidelity and colouration, both of which are integral to Sánchez’ work, throughout the process.

Chromie Squiggle #8107

Snowfro's debut Art Blocks series is venerated in print.Chromie Squiggle #8107 celebrates the ‘Ribbed’ trait of Snowfro’s Chromie Squiggle series. A personal favourite of the artist, the trait symbolises layers of the human mindset. The black ribbed layer shrouds the rainbow layer, inferring how a layer of guardedness can often prevent our inherent joy from fully radiating.The print process of the edition replicates how each Chromie Squiggle is digitally arranged. Each of the 10,000 digital squiggles were created with a standard full spectrum rainbow layer, adorned with a trait on top. Here, the rainbow layer is masked by black ribs which are applied with a silkscreen layer.With the artist taking no profit from the project, Snowfro hopes the print edition will allow the broadest possible audience to enjoy Chromie Squiggles with a high quality physical representation.The exact edition size will be determined by the number of prints ordered in the 7 day release window. When this window ends, artworks will be printed and shipped worldwide free of charge.

Perfect All Alone Ironic

Tomokazu Matsuyama reflects on the paradoxical pleasures of solitude.In Perfect All Alone Ironic, wisteria, lilies and irises surround a contemplative lone figure. To create the edition, Matsuyama worked closely with printmakers to introduce new layers of detail to an already-intricate painting. Floral motifs traced in silver echo the lavish textiles that enshroud his lakeside subject, while snow-like spots add depth and – in contrast with verdant foliage – a sense of seasonal surrealism.Characteristic of the artist’s original paintings, an irregular outer edge adds a final stroke of arbitrariness. Prints arrive float-mounted in bespoke white frames, contoured to match.

Diamond Vibration (Caught by the fuzz)

Indigo and aluminium converge in a diamond print by Jonny Niesche. Diamond Vibration (Caught by the fuzz) continues the artist’s explorations of colour, evoking emotion through seamless gradients and seductive simplicity. Ombre hues build on colour spectrums observed in nature – in particular the surroundings of his Australian coastal home – as well as childhood memories following his mum around cosmetic stalls. The pale outer edges gradually seep into a buffed aluminium border, which plays on reflective metal qualities seen throughout the artist’s practice.

Ruki-chan (Black)

Kotao’ Tomozawa's interrogations of the uncanny continue in an edition of sculptural slime dolls.Ruki-chan appears as if picked up by an ankle, Achilles-style, and dipped head-first into a pool of slime. A recurring character in Kotao’s practice, Ruki-chan is based on her childhood doll – a companion who played a part in her early experiments with slime. The bronze sculpture is covered in a layer of urethane paint, contrasting a black gloss coating reflecting the hyperreal shine of slime. Absurd, intriguing and yet elegantly-minimal, Ruki-chan continues the artist’s mediations on senses and texture.

The Earring

Arghavan Khosravi threads cultural commentary through Surrealist beauty in The Earring. The assemblage print edition makes use of recurring motifs seen throughout the artist’s two and three-dimensional practice: ropes, obscured facial features, ball and chains, all framed within an overriding beauty and delicately painted details. Khosravi spins influences from Persian miniatures, textiles, Greco-Roman figures, merging to reflect restrictions experienced by the artist in Iran, where she was born.

GIANTS, High jump in Rio

A miniature giant by legendary photographer, JR. In his ongoing Giants series, JR takes over buildings and monuments worldwide with enormous black and white portraits. The project began in Rio de Janeiro during the 2016 Olympics – championing determined world class athletes who didn’t quite make the cut. Mohamed, a Sudanese high-jumper, took his place on the roof of a foreclosed apartment building overlooking the ocean. A first-of-its-kind sculpture archives the moment at a domestic scale. The figure, printed on acrylic, can be affixed to a scaffold made from welded steel rods and displayed in isolation, or placed on top of a bespoke plinth which doubles up as an edition box. “All my works are ephemeral. If you go back to Rio it’s not there, but it’s there in people’s minds. For the people who haven’t seen it, here is the proof that it at some point existed.”Watch the accompanying film to hear JR’s reflections on scale, scaffolding and the importance of protecting his naivety.
