Mr Rubin Hollatz who this certificate was awarded gave it to me as a gift. His name was signed on my 1967 original warranty booklet as the selling dealer's authorized representative. Through some searching on my own I was able to find him. He is now over 80 years old. He worked at Penrose Chevrolet (where my 67 was sold and delivered on 4-1-67) at Parkers Priarie Minnesota for 41 years. Anybody every heard or know anything of the 4 zone managers that signed this special certificate that was presented to him?
