Mt. Washington Summit House. A stationery letter form personalized for the Mt. Washington Summit House, with a bright color illustration, with red lettering, of the famous New Hampshire hotel above the clouds on the first page of the bi-folium, 9 in x 5 ½ in. The printed year date of 1892 was hand-corrected by the author of the letter to 1893. Dated July 31, 1893, Caroline E. Green’s letter to her friend mentions that “we have a clear-day on the summit.” The back of the folded sheet has the geographical description of the hotel and places of interest which could be visited from the hotel. Situated 6,300 feet above sea level, Barron & Merril, the proprietors of the Mt. Washington Summit House, claimed their hotel stood on the highest point “east of the Rocky Mountains and north of the Carolinas.” The hotel had room for 200 guests as well as the conveniences of telegraph and post offices. Among the places to be visited from the hotel was the U. S. Signal Service Observatory. Built in 1853, the Summit House is believed to be the oldest mountain-top hostelry in the world. Traces of an old one-time fold, otherwise fine condition.
