This auction is for a lot of 500+ US Navy produced recognition slides.  I only looked at about 20 slides and the dates were from 1956 to 1960.  Some may be older, some may be newer.  Showing ships, planes, submarines from USA, USSR, Japan, Korea and I would guess other countries.  The two boxes hold 600 slides but a few are empty holders.  Email with questions and thanks for looking. ALL GAVE SOME....SOME GAVE ALL....THANK A VET FOR YOUR FREEDOMS....
