I just ran across the APBA Baseball Card 12 List and Publication Data web page.
I found a link to it on Between Lines last night. It’s a comprehensive list compiled by Doug Burg of the Yesterday APBA Baseball League. I should have seen it when Doug sent us his league profile a couple weeks ago.
Starting with the 1883 season, the list is sorted chronologically by season, Doug’s list has pretty much any bit of quick info you would want to know about about an APBA Baseball Card set.
Including:
- # teams
- # cards per team (including # of XBs)
- year set was published
- whether Master Game symbols were issued
- and yes, where the 12 is located on the card
Doug added some useful (or at least interesting) information such as what years result numbers (such as 42 or 14*) came into play.
thanks, Doug!
[edit: the updated 12 list is now here.]
