On a budget of $100K and just to have until they pry it from my cold, dead fingers?
Prewar: Max Stein PC of Wagner. Just a unique image I've always liked.
Postwar: 1948 Leaf Rocky Graziano. For those who don't know, it was pulled from the issue and replaced but a few got out. I haven't seen one auctioned in some time.
Memorabilia: Original Exhibit card artwork for the Cassius Clay card. It sold recently for $28,481.
