This map was issued for 1974 by the Sun Oil Company. At that time I don't know if the service stations gave them to their customes or sold them to their customers. There is no UPC nor is there a price on it which might make me think they were given away at the time. This particular map was used and has smudges on it. I did not attempt to work on cleaning it with an eraser. The reverse has an ad for Sun Travel Club and a Sunoco or DX travel card. The maps seems to cover from Lake Michigan to Cincinntati and then across to Washington DC and North to the border and a little beyond. We must collect 6% Pennsylvania Sales and Use Tax at checkout. Thanks for stopping by!
