I tend to swim in a different end of the hobby pool than most folks here, so while I do bid and win at various auction houses, it generally isn't any special or noteworthy.
However, last night was an exception. I won a lot of 4 signed 1961 Fleer cards.
Three of the cards are duplicates to me and commonly available and affordable. The Bobo Newsom, though, is what I wanted due to it's rarity. Newsom died young (age 55) in 1962, so there was a really short window to get this card signed. It is the 73rd signed '61 Fleer in my collection, out of 96 that are theoretically possible.
