The 1938-39 W711-1 Cincinnati Reds team issue sets may be the closest to perfect sets I've ever come across: Great team, beautiful design, relatively rare, relatively inexpensive, and one impossible-to-find white whale. Perfect...

For my money, there is no more beautiful set than the 1909-11 T212 Obak minor leaguers...

Doesn't get much better than these little works of art. Topps eventually crushed them in their bid for global supremacy, but LONG LIVE BOWMAN!!!

This bad boy just arrived, and I couldn't be happier. You may be cool, but you will never in your life be the Chick King on his '59 Topps card cool...

Doesn’t get any more artistic than the T3 Turkey Reds. Depicted here is Slim Sallee, who won 19 games for a Cardinals team that only won 51 games in 1913, and who went 21-7 with a 2.06 ERA for the 1919 Worlds Champion Reds...

"Sallee had a rare and unique delivery known as the 'cross-fire.' Wearing his cap yanked low over his eyes, he went through a slow motion procedure that hypnotized batters and exasperated umpires. Placing his right foot to the third base side of the rubber, while keeping his left foot on the rubber at the extreme first base side, Sallee cranked his arms straight up behind his head, leaning far back as he threw his right leg skyward to a set position. He would then step or plant the right leg at a 45-degree angle between first base and home plate, finishing his follow-through on the extreme first base side of the pitching mound, delivering the ball at one of many possible arm angles. Batters constantly complained that it looked as if Sallee’s ball was arriving from first base."

Sallee “had the best control of any southpaw that ever curved a ball over the plate.” - HOFer Roger Bresnahan
