Holy Moly.
This is fantastic.
Heritage Auctions has various preview images up for their upcoming Platinum February auction and it includes this rare circa 1932 Brooklyn Dodgers warm-up jacket said to have once been owned by All-Star outfielder Lefty O'Doul. Per the auction description:
Extraordinarily rare garment is a white whale for the advanced Dodgers collector, as the team wore this rather staid version of the logo letter "B" on its uniforms only two seasons--1931-32--otherwise favoring the familiar Old English style that held sway throughout the bulk of their Ebbets Field residency.
