Unique one of a kind ATC ACEO - Base is 140Lb acid free watercolor paper. I've added inks and acrylic paints and floated metallic powder in resin. I've also added some sort of weight scale, a vintage key, some brass chunks from a watch shop, a base of silver metal and one of my ceramic clay face shards. The entire piece is encased in resin. It is a one of a kind original collage/assemblage signed DSprague. ATC ACEOs are a wonderful and affordable way to collect original artwork direct from the artist!
