A photos like this, what they call a flying boat, more about it below the photo:
It turns out to be a rare prototype flying boat from the WW2 era, called the Latecoere 611 AKA "Achenar", only one was made for the French Navy, and if flew 1600 hours from 1939 to 1947... And I probably only paid $1 for the photo, it's probably not worth that much, or maybe it is given the subject matter... I just love researching things like this...
I know I should be an historian for a living
Easier said than done, I often call myself an amateur historian... If you care enough there is a brief Wikipedia entry and other articles about it "Latecoere 611"
