It is a blog of professional photographs mostly 50-100 years old. Among the MANY fascinating pics it has a lot of original seldom-seen pics from the US homefront of both World Wars, including Tuskeege Airmen, Rosie-the-Riveter types in defense plants, relocation camps etc. There are also Civil War photographs, old cars, trains, and many other subjects to interest just about anyone.
