Went to visit my youngest son who is currently stationed in San Antonio TX, they have two nice museum's on base if you get down that way for a visit. There is a medical museum and a military museum; just want to share a couple of pictures of one of the displays. (I have some pictures on my phone, havn't figured out how to post them here yet.)
North of the base there is the National Museum of the Pacific War located in Fredericksburg, Texas. Great museum you can spend two days in there; saw this 1928 overstamp in one of the displays in pretty nice condition.
