Great cover art about transforming a blimp into an aircraft carrier.

This is quite interesting to view all the depth Popular Mechanics goes into WW2. They look at military and civilian war technologies in ways most history books gloss over.

The cover title - "More Power for America" is about how America had to focus on utilizing different materials and methods to maintain electrical power due to shortage of materials typically imported. Also, a great article on waterpower.

Many other great articles about the war efforts including technology used for beach landings, civilian defenses in Britain and much more. 

Also has a Camel ad featuring Jo DiMaggio and other fun old advertisements.

Very good condition for a magazine of this age – good color, no missing pages and minor wear. The most obvious blemish is the faded spine color.
