Original Vintage Bank on Heinz 57 Placemat? Poster for Signage? Copyright 1978

Description

This is an original Heinz 57 item that I am not sure what exactly it was used for, but it has a copyright date at the bottom of 1978, and I have been in this business for over 40 years now, and I have never seen one of these before. Was it made to be used as a poster for special sales? Was it used as a place mat, or under glass on a desk at the Heinz Co for employees? All around the sides and bottom are images of the products they sold at the time. The main thing that floors me is the size - they are 22" wide and 17" tall. I recently bought a pad of these in a shop, so I have a number of them for sale. If you have an idea of what these may have been used for, let me know. If you buy one or more, it will be rolled and sent either in a box or tube for the safety of the item.
