I bought a postcard about a month ago on eBay. I didn't buy it because it was for genealogy, but because it was a postcard that originated from where many of my family members did. However, I do think it is important to share because it may help someone else in their genealogical search. Here are the scans of the front and back:
The postcard was written to a Mrs. Theodore Powers in Vermont from a woman named Linda [?] Ann.
