Undivided back, used postcard. Postmarked July 29, 1906 from Sault Sainte Marie, Michigan. Publisher: S. W. Kirvan. No. 1820. Made in Germany.
The addressee, “Miss Ada” of # 89 Second Avenue, Pittsburgh, PA, was not found in census records or city directories. What’s her surname? Hmmm. Dempsey? And 89 could have been only an apartment number, and maybe Ada was a middle name. Still she wasn’t located. So, moving on to some other points of interest….It’s a beautiful card, nice colors, slightly heavier than many postcards, but about the description: It must have been a misprint, and should read as: Old American Locks, 1855 to 1881, Sault Ste. Marie.
S. W. was Samuel W. Kirvan, found as such in a Google book snippet for “Souvenir of the Soo: Scenes Around La Saut De. Ste. Marie, Michigan” described as four pages, for which Kirvan was author and publisher. More on the publisher in the next post.
