This is a very rare advertising window display piece featuring Jackie Robinson. It advertises the 1952 Topps set and is thought to be one of only two known to exist.
Here is one of the more unusual Dodger related items in the auction. I'll let the auction description describe it.
Three pounds sounds light. Or squishy, in the case of the human brain. But when compressed into a dense, 3"-diameter ball made of pure cast-iron, those three pounds have the heft of a mini-cannonball. Accompanying this deceptively weighty silver-finish ball (Near Mint with a tiny bored mounting hole) is an undated handwritten LOA from a New York photographer named Jack Barry, who writes, "Many years ago the Brooklyn Dodgers gave me a cast-iron baseball to help an ailing shoulder. To the best of my recollection the year was sometime in the mid-fifties. The purpose of the weighted ball was to keep a pitcher's arm from tightening up after throwing for more than three innings. Carrying the heavy ball kept a player's elongated muscles from tightening up. By using the ball it was supposed to take less time to warm up—for the next game."
Here is a phenomenal panoramic photograph of the first game of the 1959 World Series between the Dodgers and the White Sox. It reads on the bottom right,
"WORLD SERIES - OPENING GAME / CHICAGO WHITE SOX - VS - LOS ANGELES DODGERS / COMISKEY PARK - OCT 1 1959 / ATTENDANCE 48,013 - SCORE - WHITE SOX 11 - DODGERS 0."
