I completed this about 3 years ago. The last couple of cards were tough to get! A bit of trivia: My daughter bought me the Ruth-Mays-Aaron card for Christmas!
This is the first set I ever saw complete -- my brother ordered it through the mail in '78. I didn't complete it until 30 years later (my brother doesn't collect anymore, wonder what happened to his?)
Here's one that a lot of collectors completed. In 1989, I came very close to finishing this set simply by buying packs at one drug store. I came 4 cards short. Finished the set years later when got back into collecting. Also, I might have a second set in a box somewhere!
