Walking on through life. Ahh! The water and the waves are on the right side of the railing.
ACEO means, Art Card Edition Original and the size is always baseball card size,
2.5 inches by 3.5 inches horizontal or vertical placement, it doesn't matter.
ACEOs may be made of anything: fabric, metal, paintings, collage, etc. The size is the key to being an ACEO.
