Here’s another cool item from Mastro’s June 2008 Classic Collector Auction: a 1955 Exhibit Card Catalog.
The only other copy I’ve seen (which could be the same as Mastro’s) is on Adam Warshaw’s Exhibit Supply Company Page.
The full text of the cover says: Exhibit’s Cards for 1955: Sportlands, Amusement Parks, Carnival Operators. The Backbone of the Amusement Arcade Business. Exhibit Supply – 4218 30 W. Lake St. Chicago 24, Ill., Est. 1901.
From the ad’s appearance, the slicks along the top appear to feature Exhibit’s Art Model Cards.
Happy collecting!
