ACEO = Art Cards, Editions and Originals.
ATC = Artist Trading Card
An ACEO and an ATC are generally the same thing. A small work of art in any medium, the size must be 2.5 x 3.5 inches. Some are prints in either open or limited editions and some are original works of art.
These adorable and highly collectable little works of art look cute framed in a small frame. They also look very chic and contemporary matted and framed to fit a standard 8 x 10 inch frame.
