Ahh......a subject dear to my heart! I have been researching Chicago area dealerships and collecting memorabilia from them for years, longer then I have been into Chicago history. I think it may have been influenced by the decade I spent in the car business.
I focused mainly on Chevrolet because I collected 60s & 70s era Chevy muscle cars as well. Nickey Chevrolet at 4501 W. Irving Park was one of the biggest high performance Chevy dealerships in the country. (Chicago also had Mr. Norms Grand Spaulding Dodge for the Mopar guys). Here is some of my rare and pretty valuable Nickey Chevrolet memorabilia.
