Recently completed a '68 Topps Game set and reached my goal of 1000 different Roger Clemens cards on TCDB. Now I'm focused primarily on completing the following sets:
1954 Red Heart
1957 Topps
1995 Topps WWF Pro Wrestling Stars
Also, always interested in acquiring Bill Dillman cards (69 Topps especially).
When trading for vintage, centering goes a long way for me, but I'm flexible.
