One White Horse, along with four other ACEO's is being mailed off today for the Canine Art Guild's ACEO challenge "Flower Power". True, these are not dogs, but we celebrate all animals. I even sent along a chicken! ACEO stands for "Artist Cards, Editions, & Originals" and the only rule is that the card size must be 2.5" x 3.5". This drawing is an original ink pen and watercolor.
