Thanks for the nice comments--Sorry about your keyboard!
Just about every card I own between 1948 up to around 1956 were cards I bought originally at the corner ice cream store or in a Mom & Pop drug store.
I had them carefully stored away in 1958 when I went off to school & reclaimed them in the '80's. My Mom was under orders NOT to throw away my "stuff"!
Good luck w/ your quest of a '52 set---it's a BEAUTY!
