Making the rounds of late is the apparently new Product Manual Archive, a Web site dedicated to cataloging product instruction booklets of the past.
The gallery so far appears a bit meager, but includes some terrific images of vintage products, as well as ads, diagrams and how-tos.
Among my favorites is a booklet published by the now-defunct United States Office of Civil Defense titled Fallout Protection: What to Know and Do About Nuclear Attack, which offers helpful advice on how to construct and stock your own inexpensive fallout shelter.
