Like most artists in the funny book biz, once in a while I'll auction off a few pages of original art on Ebay; usually when I need some extra cash to handle whatever surprises life may throw at me. Other times, my cocaine and hookers funds run low. For whatever the reason, eBay has usually been a problem-free way to make a quick buck.
I'm guilty, at times, of being a bit slow on shipping artwork out. Thanks to the influence of Tom Nguyen, I usually polish off most pages in photoshop these days. Most of the art is done physically at my drawing table and then, to save time, I'll scan and finish the work on the computer. I'm not an Adobe master so basically, this amounts to spotting the blacks and doing the clean up in photoshop (not that I ever make mistakes), then templating and uploading the finished art to DC.
