I'm posting this link in the design area -- but it's regarding advertising design, not vehicle design. This:
http://www.adclassix.com/caradsindex.htm is a
great reference for vintage automotive advertising from 1914+ (it's also a store, but I'm not posting for that reason). Like with all cultural study, it's interesting to see where emphasis was placed over the years (value, safety, speed, style, brand, patriotism, etc.) and how those attributes correspond with society at that time. There are no Tucker ads -- but check out some of the advertising of the big 3 during that time period...
