+1 for the 1952 Bowman. I LOVE this card (here's mine). I also really like the 1956 Topps (although I don't own one...yet). I think 1956 Topps has some of the best images for a LOT of players....the large profile pic with full action background is great (the Jackie Robinson, Clemente, and Mantle all have great looking cards in that set).
No one has mentioned 1951 Bowman in this thread yet. Personally, I think Mays looks too "angry" in that one. Maybe others do too, which is why it doesn't make the list?
