It looks like Maury Wills is about to steal a base with Ernie Banks holding him on.
Featured above is a vintage, circa 1960's, Kodachrome 35mm Slide Transparency of in-game action between the Dodgers and Cubs. (Auction Link Here) Unfortunately, it is not dated but we do know it was taken at Wrigley Field, and by the looks of it Maury is about to steal one of the 29 bases he stole in Chicago throughout his career. The photo was taken by noted Chicago area freelance photographer Lee Balterman.
