As a set collector who grew up with Topps cards, my first dilemma was whether to expand to other manufacturers. I eventually decided to do Bowman and Fleer as well. Next decision was whether to stick to base sets or do variations and packs. Next decision was whether to do insert and issued test sets. Next was whether to do unissued test sets. The last one will be a never completed project.
For a long time I managed to hold the prewar line, but finally started on the 1923 Fleer set because it was part of my Fleer "run"
