I just recently got back into comics after something like a 10+ year hiatus. I'm currently following most of the Bat-Family titles, and I'm particularly enjoying Red Robin.
Well, a few months back I took a trip up north to our nearest comic shop (about 50 miles away from my home) to purchase all of the available issues of Red Robin. By this time, there had been 3 or 4 released, I think. Anyway, he was out of Red Robin #1, all but a signed variant copy which I ended up picking up for $20.
I've been unable to find a definite way to judge to value that an autograph gives to a comic. There are people selling it on ebay for anywhere from $50 to $149 for the signed variant cover, with one guy even claiming that there are only 25 of these in existence.
The other problem I'm having is that I can't really identify who has signed it. Here's a picture I took of it (not the greatest quality, I know!):
I'd really appreciate anyone's input on this!
