Divided Back, Real Photo Postcard, unused. Circa 1907 – 1918.
Per Playle’s (a great reference for dating RPPCs, thus we use it all the time) this particular style of AZO stamp box, with all four triangles pointing up, is dated at 1904 – 1918, however, since it’s a divided back card, it would need to be December 1907 at the earliest. The type of watercraft is, for me, non-boat expert that I am, in question. Houseboat…?…. maybe, maybe not. In any case, we see her name on the bow, “Sea Gull.” And there’s the vague image of the skipper at the helm, standing, facing the sun. Amidships (can this term be used for small craft?) we see the silhouette of a seated man in a hat. On shore, in the background are some buildings and a large stand of evergreens.
