We are grateful to Wikipedia for this information, which we have only slightly abridged:  “The Elton Hotel is an early 20th-century building in the Second Renaissance Revival architectural style.  It was built in 1904 to replace a lavish hotel lost in a fire that destroyed much of downtown Waterbury two years earlier.  F. Scott Fitzgerald was a guest, and James Thurber is said to have written “The Secret Life of Walter Mitty”, during a stay.  On the eve of the 1960 election, John F. Kennedy gave an early-morning speech from the hotel that was credited with helping him win Connecticut.  It continued to be used as a hotel until the early 1970s.  In 1983, it was listed on the National Register of Historic Places. Since then it has been converted into professional office space and senior housing.”  There is a caption on the front bottom but you need to look hard to see it.  The card was mailed in 1909, with clear postmark and a stamp whose corner is there, but torn.  Grade: 3
