1954 Double-Side Full Color Centerfold ad Standard PUrple - Red Crown #1107

This original 1954 Ad from Standard Oil Company highlights their newest Red Crown Gasoline which was colored Purple.  The ad therefore is printed in white and purple, and it is a 4 sided double sided centerfold ad, very unusual.  The 1st image shows the first page, the 2nd image shows the center pages when the ad is fully open, and the 3rd image shows the back page.  When closed the ad measures 10 x 13 and fully open 13 x 20"  I great addition to any Standard Oil Advertising collection for sure!
