Below is a picture from Stavanger Harbour, taken during the 2nd World War, in 1939. The original is located in Maryland, USA and belongs to Arthur Andersen. It is 24 x 36 inches and one can see a submarine (probably Nazi) in the lower left. The photo is most likely American (possibly an intelligence photo?) and a US merchant ship is scratched out of the negative 1/3rd from the top on the left. Arthur's grandfather, Osmund Osmundsen, got this photo somehow - maybe through business connections. You can read more about Osmund Osmundsen here.
