I went back and looked. I started this quest when I sent some cards out to a public signing in June of 2012. So, I've been working on this for over 4 years. While I have been moving inexorably closer to completion, it has been something of an asymptotic approach. For those of you versed in math, you know what I mean. For those of you who aren't, no worries. Here is an asymptotic curve:
The Siebern, the first such example I have ever seen, came to me at the bargain price of $15. So, now I have 56 signed 1963 Fleer cards from the 66 card set. Who do I still need?
You can probably see what I mean about this being an asymptotic quest. With Mays, Clemente, and Adcock (the card itself was short printed) on the list, I have no reasonable expectation that I will ever make it. But, that is okay. I am pretty psyched how far I have made it.
