This is probably a long shot, but I would love to trade my doubles for the 1951 Topps Blue/Red Backs I have. Some are in really good shape, and some have severe creases! I am trying to put together the set and would like to trade for one's I don't have. However, I would also be willing to trade for HOF baseball vintage, but I would also look at on-card autos for HOF players. HOF rookies are also something I collect for all sports. I don't post here much, but I use BO too much! I have iTrader feedback there and can also share my eBay name for trading confidence.
