Didn't get them at the National but recently snagged a few of the Sohio Cleveland Browns premiums from 1949.
Here's my list of AAFC football cards/premiums. There isn't a lot out there from the AAFC ... what else is on your list? We should start a thread on AAFC items. I have some vintage photos as well.
1946 Sears Browns
1948 Colts Matchbooks
1949 Silbers Bakery Colts
1949 Sohio Browns premiums
