Ed,
Congrats on your quest...seems like you're making nice progress. '52T is clearly the iconic post WWII baseball card set. Great looking cards and of course the challenge of the high numbers.
My dad and I are insane enough to try to collect it in autographed form and I sincerely believe that even if I live to a ripe old age, I'll never complete that quest - but it sure is fun to try!
