Playball 39,40,41. Goudey 1933, 34, 35 (4-in 1), 1936 (black and White) and 1938 Heads Up. I think any Goudey Wide Pens and other send away cards do not count. 1934-36 Diamond Stars. Cracker Jack, T206, T205, E90-1, E91 (yuck!), 1903 Breish Williams, N300, N29, N28, N172, N162, N173 and N175 (are probably debatable).
I only collect from main sets too, and I only will.
