Description

Vintage Cronstroms Cooler Marlin on Front possible Hamm's promotion.
Very awesome cooler. The inside tray and drain plug is missing. The padded top is an amazing vintage blue. It has a few scuffs and dings as you might expect for its age. Overall its just a great looking piece.
We were told this may have been part of a Hamm's Beer promotion. Something about fishing with the Beer bear... But haven't found any solid references to it yet.
Great Cronstroms Cooler - no mater how you slice it.  Please see the photos as they are  part of the description.
