It's simple really. Just list the five people/places/things you'd like to see in 2012 Topps Allen & Ginter, and post it to Twitter with the following hashtag: #2012tang (I tried #2012ta&g, but it didn't work).
Or, just post your five in the comments.
Yeah, I fully realize that 2011 TA&G ain't out yet.
This is called "long-run planning."
Oh, you want to know who's in my TA&G5?
