What is an ATC, an ACEO and a Sketch Card?
They all have one thing in common--they are original art that measures 2-1/2 inches by 3-1/2 inches. ATC stands for Artist Trading Cards, and they are usually traded to other artists. ACEO stands for Art Cards, Editions and Originals. These cards along with Sketch Cards are usually sold. They are a rapidly growing hobby and tons of fun!
