“Pittsburgh for me on Halloween.” WTF?! Could someone from Pittsburgh explain this to me? Why Pittsburgh? Why not Salem? Perhaps this is part of a series of cards, one for each city: “New York for me on Halloween”; “Boston for me on Halloween”; “Slippery Rock, Pennsylvania, for me on Halloween”? Similarly mysterious is the artist: “Lewis.” I have no clues to her/his identity.
The date I can guess at as circa-, but post-, 1915: possibly as late as 1925. It is a cute image, and nice lettering on the front, but the back is the give-away: it is divided, very clearly, and the font is a roman serif. It is a no-nonsense arrangement. The lack of any swirling or elaborate rules and writing on the back suggests that it is post-Art Nouveau, or early Deco. The writing on the front seems early Deco to me (there is a hint of serif, but it is mostly strong uprights). And while our witch is in classic 1890s-style clothes, the colours are dull and the printing is a simple two-colour process, which we see early (pre-1905) and late (post-1915), but not often in the middle of the postcard boom. Since the back rules out an early card, I am guessing it is late: WWI-period or just after.
Which brings me to the image. As I said, the composition, clothes etc are all ca. 1890. There is a ruffle under the pointed hat, a corseted top, close-buttoned, with (I am guessing) mutton shoulders, but short sleeves; a long drop on the skirt, heavy stockings, and buckled shoes; and a cape! All, seemingly and appropriately, in black. And then there is the minions: the black cat (the witch’s familiar) on the broom and half a dozen bats: one far too close for our feline familiar’s comfort.
What is missing is any naturalistic detail, no landscape or city-scape, no clouds, sky or stars. The moon is also without detail, it is just a round disk. To me the whole thing looks like a logo, like the Salem-city logo, which appears on shirts and caps and coffee-cups. Perhaps there is an organization or sports club in Pittsburgh that uses a witch like this as it’s logo? If so, it might explain the caption!
