I was ashamed that I did not have my own copy of a 1932 map for Part 2 of the map series.  So... I picked up a few.  Low and behold, I found a back variation.  Both are Rand McNally, both are 1932, but have different backs.  I can find NO other differences.  Also, I had not heard of the “Feeble Gas” saying before either.  What’s up with that?  Note the comment that Gulf Supreme was 25 cents. Imagine, the empty can sells for over $200 now!!!!!!
