Two World War II Treasure Island, California Radio Amateur Club 10 x 8 photos.  Treasure Island in San Francisco Bay was a World War II military base.  What helps date the photos is the sign on the wall that shows a Navy Sailors hat and states “KEEP IT UNDER YOUR HAT”.  The photos show many different types of 1940’s radio equipment.  One photo has a sign that states in part

“TREASURE ISLAND, RADIO AMATEUR CLUB”

One photo has a crease in the middle, top to bottom and a ½ tear at the bottom of the crease.  Both photos have pin holes in the four corners from being pinned to a wall or something. Please see the other vintage items I have listed on eBay.  Thanks for looking.
