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.
