I was bored, so I pulled out a business card sized piece of pressed cardboard and did some simple art. I kinda wish I had done watercolors on this, but it's not too bad for prisma colors.

Total size is 2 1/2" x 3"

I have 19 more of these cards, I plan on doing all kinda of things on them. This is up for sale if you want it, asking $10 (includes postage and it's signed on the back)
