Looking for the source of my evasion silk map

As you can see from the picture above, I procured a silk map some time ago through an online auction. I'd like to determine the year it was made, to confirm whether the auction description is accurate (it refered to it as a US aircrew evasion map of 1943-vintage). Has anyone out there seen something similar, and knows the genealogy?

Book reviews

It has been a slow couple of weeks for the project. I've spent the majority of the free time available just thinking about random issues and working on drafts of the outline I have so far. One thing I have been pretty aggressive on is reading as many book reviews as I can get my hands on, with an eye towards ones written on military history books. They serve as an excellent gauge for me on the path I think the outline needs to take. Each review has to be taken with a grain of salt, but they are rather illuminating nonetheless.
