WWII Occupation by Japan Paper Money???

Ok fellow downsizers buckle up as we are ready to go back in time! Very appropriate for this holiday weekend. Memorial Day. Remembering the ones who gave their lives for the freedoms we enjoy today... This trip takes us to WWII 1940's years when the Japanese Government occupied the Philippines and other countries  and the owner of this bill somehow got it and brought it back home. In pretty good shape! While cruising the internet gathering info I found this interesting info. Check it out!

If you like James Bond/US type of info..hmmm is this really Japanese paper money or not???

I have not found out what the P/AH stands for or what the two punched holes were for. Wonder how this owner got this bill? Wonder how the Japanese government got this money printed fast enough to use. Anyway, thank you previous owner and all the others  for going there and protecting our country's freedoms, ideals, dreams and opportunities!

If you are interested in becoming the next owner of this 65+ year old bill:
