An old postcard showing a colorised aerial photo of Seattle and the Puget Sound. Points of interest and the ferry routes of the era (pre-Washington State Ferries, which only commenced service in 1951) have then been added to the image.

It’s these ferry routes which allow us to date this charming postcard to somewhere between 1935 and 1942. The little Fletcher Bay to Brownsville ferry route (centre left on the photo) only operated between 1924 and 1942, while the Colman Dock (Seattle) to Manchester route only ran after 1935, when the old eastern terminus dock at Alki Point washed out.
