Just four ATC's I made using various stamps and products.
Artist Trading Cards (or ATCs) are miniature works of art 21⁄2 x 31⁄2 inches (64 mm× 89 mm) in size. 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, paper cuts, found objects, etc.) or even metals or fiber. The cards are usually traded or exchanged. When sold, they are referred to as art card editions and originals (ACEOs).
