Though this unused card doesn’t specify the cabin is in Vermont, it gives plenty of clues.  To confirm, we looked, and found this in Wikipedia:  “The Hyde Log Cabin is a historic log cabin on U.S. Route 2 … built in 1783, and occupied by the Hyde family for 150 years. Believed to be one of the oldest log cabins in the US, it was added to the National Register of Historic Places in 1971.  Grade: 1
