Thanks for the comments!
Regarding the signatures, the pricing was $15 per signature on a comic book, or 25$ (or $35?) if you wanted the signature to be CGC-certified. (I declined that offer.) There were a bunch of large-sized posters which I think cost a bit more per signature. Anyhow, when Steranko finally got around to the signatures, he asked, "Can I sign this to a specific person?" or something like that. I said, "Nah." He said, "Okay."
I probably would have paid extra to avoid the personalized touch, if it had come to that.
My experience was a few years ago, and at a smaller show, so his prices have likely just gone up. He was free for personalized autos (but I think those were limited), $5 for unpersonalized, and $15 for CGC books. Thanks for the more recent pricing info.
