The 1966-68 Batman TV Show had several episodes where the Caped Crusader and Robin were seen hoisting themselves up a building via the "Bat Rope" and invariably encountering a celebrity of the time poking their head out of a strategically placed window.  Well the Dynamic Duo had nothing on Joe Sewell as see here on his E220 National Caramel rookie card as he seemingly climbs the infield chasing after a hot grounder. Graded SGC 3, one of two at that level with none higher in their pop report, this card has some corner rounding and a very small crease at the top middle border.  The reverse has never been mounted, with just a spot or two of light soiling from handling way back when.  A superb looking example for the grade.
