I just got a great original Lincoln ink drawing on eBay:
I wasn't sure what to expect because I'd never purchased art on eBay before, and didn't know how accurate a picture of a picture would be. I was extremely happy with what I got.
Watch this seller: retoyman. Every now and then, he's got some interesting Lincoln drawings, including some in modern-day attire. (If he's selling anything related to Abraham Lincoln, it will show below.)
