And if you're a collector, then you understand what that's like.
In order to keep adding to the collection you might find yourself expanding the definition of "card".
In my case, I started to collect felts, which I had never really been that interested in. I find myself looking at pins and discs and chips a little more often now, too.
Postcards have always been on my radar, but they are rather expensive and show up rarely.
And then there are photos.
Photos can be an interesting way to expand the player collection, and can be affordable. In the case of Gibson, that doesn't really apply to photos of his playing days, but if you're willing to collect photos from his managing days, then you might be surprised what you can find.
Below is the photo that I most recently added to my Gibson collection. I found it on a photo dealer's site while searching Google for...I don't even remember what ;)
This is, hands down, my favourite Gibson photo of my collection. The back has a Central News Photo Service stamp and the caption that was included with the photo says:
Specially posed picture of Gibson, manager, taken in the "dug-out" at the Polo Grounds, Ny., Aug 25.Oddly, it doesn't have a year. Gibson managed the Pirates from 1920-22 and again from 1932-34. At some point I'll go hunting through some New York papers to try to put a year on this. It shouldn't be too difficult, but for now I'm willing to let it remain a mystery.
