Here's the story behind the print:

 

"I've been painting found objects for several years and when I temporarily moved to Crested Butte, Colorado, in 2009, I went in search of something new to paint. Luckily, an abacus caught my eye in an antique store in nearby Montrose; it has been far and away my favorite project. It took about four years to come up with enough ideas (and time) to paint the 100 beads but it was a sheer pleasure.  I thought I'd share the wealth by selling prints of the beads and donating any proceeds to charity."  - KD
