This card was published by Illustrated Postal Card Co of New York and Leipzig. Perhaps that is why we have a bit of glitter acting as string-courses across the buildings of Shelton Square. It is snowy and we see part of a street car and the tracks. We also see a horse drawn cart. Obviously an artist colored photo, the shading is truly beautiful. An interesting feature in the white border to the right of the card which I think helps the picture. The card was addressed but never posted. The addressee was written in pencil. It does call for a one-cent stamp. This surely is from the early 20th century and that fits with the collection from which it came.
The card has no bends or scrapes, but is a tad dirty on the white and appropriately aged on the back coloring.
