watercolors on a watercolor ATC.
Artist trading cards (or ATCs) are miniature works of art about the same size as modern trading cards baseball cards, or 2 1⁄2 by 3 1⁄2 inches (64 mm × 89 mm), small enough to fit inside standard card-collector pockets, sleeves or sheets. The ATC movement developed out of the mail art movement and has its origins in Switzerland. Cards are produced in various media, including dry media (pencils, pens, markers, etc.), wet media (watercolor, acrylic paints, etc.), paper media (in the form of collage, papercuts, found objects, etc.) or even metals or fiber. The cards are usually traded or exchanged. When sold, they are usually referred to as art card editions and originals (ACEOs).

i used more paint and less water than i usually do, so the result is much more vivid and deep.
