8" x 5", 3 pp, usual mail folds, on Mayor's Office Letterhead with NYC crest, some ink feathering to signature. John Thompson Hoffman (January 10, 1828 - March 24, 1888) was the 23rd Governor of New York (1869-72). He was also Recorder of New York City (1861-65) and the 78th Mayor of New York City (1866-68). Connections to the Tweed Ring ruined his political career, in spite of the absence of evidence to show personal involvement in corrupt activities. He is to date the last New York City mayor elected Governor of New York.
