Thank you all. It's been so great getting to know so many good people through the hobby. Brian, I have somewhere around 50+ duplicates as well. So, one day, when I get a firm count on them, I'm likely going to pick up around 25 of his cheaper cards to make it an even 500 (I'm assuming I can still get those ugly checklists for $3.00 a pop). Maybe a couple of checklists.
Mike, I'm happy to help. I'll let you know when I see a nice Bancroft Tiddler for you!
I'll shoot you a email later about the Life Magazine as it just arrived.
As for modern, the companies have made it really difficult to be a collector these days. Mantle had a ton produced during his career, but the modern stuff far outweighs it. There are some 52 Topps style cards I may get at some point though just because of the aesthetics. But, I don't plan to put anything really serious into it.
