|Mrs. W.W. Hosmer, postmarked from Camden, 28 Aug 1907|
The card is addressed to Mrs. W.W. Hosmer. There is no signature. But, who is "Mrs. W. W. Hosmer?" Hosmer is a well-known name in Deer Isle. George L. Hosmer wrote "An Historical Sketch of the Town of Deer Isle, Maine" in 1905, the definitive tome of genealogical and historical research in that area.
I wondered if they were related, and if they were neighbors of my family at some point, on Deer Isle. (And okay, one likes to fantasize that the nameless "Sender" may be one's relative. Chalk it up to "thinking outside the box," or just plain dreaming!)
William W. Hosmer and Anna M. Hosmer are picked up on census reports from 1900 - 1930, in Bangor, Maine. Wm. was born in 1856, and both were born in Maine. William is a carpenter.
They have one son Edgar (who marries 'Doris B.' and they have one son in 1930: 'Harold E.')
For all intents and purposes, they do not seem directly related to the Hosmers of Deer Isle, but they are mysteriously absent from records, before 1900, and thus far, after 1930.
Southern Maine, and all of Maine really, is a mecca of antique stores, and almost all contain some kind of postcard collection, large and small, usually categorized by town. (My favorite source actually has a nice chair placed in front of their huge table of postcards, so you can sit back and peruse in comfort.)
Finding a postcard that is significant to your own genealogical research is rare and the browsing can be a practice in "Be Here Now" kind of patience. However, I would suggest: don't count it out entirely. At the very least, you will find fascinating images of the past, all kinds of messages conveyed, and possibly a clue to further research for you.
