Mastro was the auction house that sold Sergio's collection. It was within the past 2 years and I believe what you are looking for appeared in their Premiere Auction Catalogue (I believe it was probably April, 2007 or thereabouts). I thought the concept was very interesting and considered doing something similar but have since decided to simply pursue the earliest appearance of each BB HOF'er. If more than one card was issued during the same season, then scarcity and ulimately price make the final determination for me.
