A recent web search for Gunnison catalogs pointed me to something in the Smithsonian Institute's American History Archives--a 1941 promotional brochure for the company that includes plans and pictures of the different models, and a press announcement from 1944 extolling the virtues of Gunnison homes. After a brief e-mail exchange, a very helpful librarian scanned them and sent them to me. And who says the Federal Government isn't efficient?!?
I found this on eBay--a matchbook advertising Gunnison homes. Ironically, Pottstown, PA (address of the "authorized" Gunnison builder) is about 30 minutes from where I was born and raised. Enjoy.
