Postwar Topps Baseball Card Trivia Part III

[Gr8Beldini]

1. Name the Postwar Topps set (pre-1980) that includes three rookie cards of guys that died before the year was out. Of course I would want you to name the guys as well.
2. The above set also contained the rookie card of a guy that died before the decade was over. Name the guy.
3. Only one other Postwar Topps set (based on my research) had as many as 3 rookie cards of guys that would die within the next 10 years. What set and which guys?

Note: I had to amend #3 (originally asked for 4 guys) because one of the 4 guys had a card in the previous year's set (not sure how I forgot that - it is a somewhat prominent card).
