This is pretty near perfect because it we have a date and a place, 15 March, 1949. 3d postage was probably quite a lot, even for Bermuda, so what mystery. St Georges is the second town in Bermuda, situated in the east end of the islands. Back then it would have been rebuilding after the war and growing its tourist industry. Only the very wealthy would have been there back then.
These stamps were produced in 1948 to celebrate the silver wedding of King George VI and Queen Elizabeth (queen mother). Many other commonwealth countries used the same print and style for their stamps.
