Here’s an old postcard my wife bought on eBay. It shows the front of The Watson House, an old hotel on Fire Island Ave in Babylon. The postmark is 1914.

The Watson House Postcard - back

…the Watson House, beautifully located on Placide Avenue is one
of the largest, and in its various appointments probably without
a rival, the finest hotel on Long Island. In size it is one
hundred and thirteen feet on the front, by forty-seven feet
deep, three stories high, with a cupola twenty feet square.
The parlors are elegantly fitted up with rich furniture, and
the dining room capable of seating two hundred persons. The
sleeping rooms are eighteen feet square, with ceilings twelve
feet high. The house is lighted by a two hundred light automatic
gas machine on the premises. Lawns, gardens,
croquet and cricket grounds, occupy about eight acres surrounding
the house.
