Vintage Ed Iskenderian Racing Cams Ephemera Chart For M.P.H To R.P.M. Rare

Description

Vintage Rare Ed Iskenderian Advertising. It has no phone numbers on it. But it has a chart on one side for determining M.P.H. To R.P.M. The other one is instructions for cooling the Ford V8. Unsure of the decade it was printed. It appears to be foldable, on the front it has the Ed Iskenderian name and the company logo. Found at a local swap meet inside of a book, that I didn’t even know they were in there until I opened the book. I found a total of four will be selling one at a time due to all are in different condition.
Comes exactly like you see in the photos.
Please examine photos closely for overall condition.
Thank you for looking.
