Cars and trucks apparently become antiques at fifty years. The photo has a what was then a brand new truck, parked among what, today, are still front line bombers. Boeing really did a good job on the Stratofortress.
I was in the USAF 1968-72 and never once saw a silver B-52. Served in PACAF and SAC; all were painted camo.
I believe this color scheme was prior to that, shortly after it replaced the B-47, which also had the silver color scheme with the SAC "Milky Way" flash on the nose.
As a kid in the 60's my neighbor flew those never knew what years he was older. Damn alzheimers took him, wonderful man.
