This past weekend, I rented a table at the SPACE comic convention in Columbus, Ohio. This particular con was for self-publishers only... so, if you had the $50 to pay for the table fee... then you were most welcome to schill yer wares. There was a lot of oddballs and oddball stuff there... it ran the gamut from extremely amateur stuff to hifalutin', introspective brouhaha.
I was pretty successful... I sold 40 books and drew many super hero sketches for cash.
Here's a link to further coverage of the SPACE con.
