Although sports matchbooks are pretty cool I don't think they are in the database since they are memorabilia and not "trading card" A strong argument could be made for them though since they are tobacco products. This database is technically the "Trading Card" database not the "Sports Memorabilia" database.
I collect: Baseball, Football, Hockey, Mostly Vintage pre1980, My Homie teams - Washington/Baltimore Teams Senators (Twins, Rangers), Expos/Nationals, Redskins, Capitals, Bullets/Wizards - HOFers - Non-sport (mostly TV shows and movies).
My Trade List is very much a work in progress
