It must have been a thing back in the 1960's to solicit picture ads from the local car dealers for the high school yearbooks. Get a commitment, then some of the jocks and cheerleaders come by and put dents on your hood...... Don't remember anything like this in MY yearbook....... But then again, I probably haven't looked at it in like 30 years... (50th H.S. reunion was last year.... I didn't go. )
