Japanese Navy Sailors WWII Photograph

This is an original, unpublished, photograph of a WWII Japanese military personnel. I came across this lot with some WWII Japanese and USMC items in a collection I bought.  I was told they came off of Iwo Jima. Many Japanese were big photography buffs and took lots of photos.  Some may be in China, where many Iwo Jima soldiers were shipped from.  Others came from other more tropical regions. The size of each photo is shown.
