I've seen the Pittsburg Plate Glass (PPG) book that Gordie refers to. PPG was a leader in working out how to curve larger pieces of glass and remove visual distortion that commonly occured with curved glass for commercial applications. Other units of PPG created various heavy-duty paints and acted as consultants to architects, building contractors among others. The book was moreorless generic with covers and certain pages "customized" for various lesser makes (as opposed to the books put out by GM, Ford and various divisions of Chrysler Corporation as well as Nash and Packard).
One of the auto-related things I have an interest is dealership architecture to see how the designs evolved (especially the art deco and "futuristic modern" places ofthe period 1934-1949). I wish I knew somebody who had one of the PPG books that I could scan for my collection of information.
For those who might be interested, here are some illustrations of dealerships actually promoted to their flag dealerships including Kaiser-Frazer:
1. Art deco building built into a berm/hill from the 1940 Buick Architectural Standards book
2. Suggested placement of display items in a showroom at a Kaiser-Frazer dealer for 1951 Kaiser
3. Medium size dealerpoint "neighborhood" K-F dealer in 1952
4 !948 General Motors architects suggested dealership design
5. 1948 Suggested merchandising fixtures and signage for Kaiser-Frazer dealer parts and accessories area of dealership
6. 1960 Dodge Division, Chrysler Corporation illustrtion of proposed new Dodge Dealership.
