Everyday the Chicago Tribune website includes reprints of old issues. Today includes several 1959 and 1960 issues. The reprints include auto advertisements from a number of Chicago area Chevy dealers. Check it out if your car was originally sold in the Chicago area. You may find an add from the dealer that sold your car. Its hit or miss, I'm still looking for a McKeown-Phallin add that I could print and add to my documents. By chance I found an add for the original construction of a house that I owned in a Chicago suburb in the '60s. Good hunting!
