Thanks! I purchased the Goodwin book but I won't receive it for another 3 weeks. I can't make it to the Nationals (they won't let me leave Afghanistan for a Baseball card show).
It's difficult to determine good vs. bad on eBay. The image qualities are poor and I don't know what to look for in the first place. I'm learning to look for contrast (I believe they mean on the card and not my computer).
I'll review the book when it arrives (I ordered the T206 book too).
