Al CrisafulliWow, that's a HUGE accomplishment! One set from every decade of the 20th century - amazing.
For the past few years, I've been trying to do one set from every year the Yankees won the World Series. Thus far I'm complete on 1938 Goudey, 1943 MP & Co., 1953 Topps, 1977 Topps and 1978 Topps, and I'm very close to complete on 1961 Topps and 1998 Leaf Rookies & Stars. I'm just about to start 1928 W502. But I can't fathom ever actually getting done.
In any event, I think you're right - a quartet of OJ, T206, 33 Goudey and 52 Topps would probably be the most enviable group for set builders.
For type card collectors, I would imagine that a four-sport HOF type set (baseball/football/hockey/basketball) would be a tremendous challenge, especially if the collector placed some limitations on how many cards from any individual set would be allowed. That would require a great deal of regional and foreign cards, and would be a heck of a challenge.
