Some more from the 1980's.
The map on the left from 1985 is darker than the one printed in 1983 in the middle.
I only know of 5 states put out on the PBA-4 maps.
An end to the "Free Map" era.
This is the last map I have seen with Marathon Company Advertising. And it is on the inside of the back cover.
I love the RWB Eagle Promo they used in stations at that time.
There have been some local issue maps with local dealer ads, but not Company Sponsored ones.
