I've finished the 1965 Topps set. They were my first cards as a kid, so it was fun to put together again. My set was 2nd on the PSA registry the last I checked.
I've gone as far as I can with the T206 set: 522 of 524 cards.
I've been working on a back run of Merkle since 2008. I'm missing one card (T215 Red Cross), and also a Street back run (missing the Lenox, Red Hindu, and T215 Red Cross). More on this in a couple weeks...
So I will need to find a new subset in 2016. Maybe something Cubs-related?
