This is a really neat fundraiser started by someone who just wanted to pitch in.

Cody Barnes is a professional portrait artist from Birmingham, Alabama. He’s offering to donate a percentage of his fees to American Atheists for any atheist customers who want to get work done:
Cody’s portraits are $200 for a charcoal, $350 for a sepia painting, and $500 and up for a full color oil painting. Cody will donate $40 to American Atheists for every charcoal, $70 for every sepia painting, and $100 for every full color oil painting.
It might make a really nice gift for a special someone. If you’re interested, Cody’s contact information (and several samples of his work) can be found here.
