Jonathan Olly asks-
I have a minor photographic mystery for you. I recently came across this postcard on eBay, showing a WWII DUKW emerging onto Pavilion Beach, with Ten Pound Island Light in the background. Do you or any of your readers remember when these tours operated in Gloucester? The caption on the back of the card reads "Amphibious duck ride from land to sea on a guided tour of Gloucester Harbor. Leaving every half hour from Pavilion Beach, Gloucester, Massachusetts."
