Vtg 60's Columbia Bicycle

Found at the estate of a former small town sporting goods store owner.   Fab vintage store advertising poster for Columbia Bicycles from the early 60's.   This is for their Tandem line of bikes and measures 32" x 21.5".   Has been folded in the center and there is some light wear from storage around the edges.
I have 5 different posters - all similar but each advertising a different line of bicycles.   I'm happy to combine shipping if you are interested in more than one.   Will be shipped rolled in a tube.
