I've donated the original art from this strip (above), matted and framed, to benefit Frankford Friends School in Philadelphia.
The retail value of the art is $200, but they've started the bidding at $50, so bid now.
As with all my originals, I print the digital lettering and panel borders on a sheet of transparent film which is placed over the original. Matted and framed, the result is similar to an animation cell. Here's some more info about the process.
Frankford Friends is an extraordinary school in Philadelphia and a very deserving organization for your charity dollars. If you've been looking for a good excuse to get an original, this is a win-win.
