What is an ACEO card? ACEO stands for "Art Cards, Editions, and Originals". They are also known as ATCs, or "Artist Trading Cards". ACEO cards are small trading cards that always measure 2 1/2" x 3 1/2" so that they can be collected in albums, just like baseball cards. They can be original artwork, numbered edition prints and photographs.
Due to the fact that computer monitors vary, the actual art may be slightly different in color or brightness.
