It is likely that this photo was taken at the Greenwich Village Garden Party in June, 1917. See

Thanks for connecting the two images of the young ladies, B-59. We'll make the correction to the caption the next time we update.

A "Miss Tiffany" is mentioned in connection with the Greenwich Village Garden Party in May, 1917: The Washington, D.C. Times reported, on May 23, 1917: "VEGETABLE PARTY RAISES BIG FUND New York People Help Woman's National Service League. NEW YORK. May 23. Five thousand society, near-society, and non-society folk paid their way into a Washington Square garden party with raw vegetables which they later bought back at prices that even the war never can force. Wherefore, the Woman's National Service League's campaign fund is richer by several thousand dollars today. Mayor Mltchel's wife got in with a young basket of carrots; Miss Tiffany gave $5 for a frankfurter and ate it- which was worth $5 more. Marie Dressler auctioned off a bouquet of cabbages, onions, string beans, and garlic tied with red. white, and blue baby ribbon." chroniclingamerica.loc.gov/lccn/sn84026749/1917-05-23/ed-...

Thanks swanq. We will update this image and the others of Adelaide Baylis.

The Milwaukee Journal - Apr 3, 1918 news.google.com/newspapers?nid=1499&dat=19180403&... reported that Col. Baylis said that Lieut. Mary Watkins would soon travel to France with Miss Ann Morgan. She was to drive trucks bringing supplies to "stricken villages."

Would a hat like the gent's on the right (fedora? homburg?) be around in the teens?

This photo ran in The Sunday Oregonian. (Portland, Ore.) June 03, 1917, with the caption: " Greenwich Village held a garden party recently under the auspices of the National League for Women's Service for the benefit of that war service organization in which Anne Morgan and other, well-known women are much interested. Greenwich Village is that part of old New York which centers in Washington Square. It is bounded on the north by society and on the south by Bohemia. Both contributed to the success of the garden party. Things to eat in Washington Square Park were served in little booths, or from stands, and one of the most popular of these was the "hot dog" stand, suggestive of the epicurean delights of Coney Island. There was a dancing pavilion and the wife of Mayor Mltchel did a one-step there to open the fete." oregonnews.uoregon.edu/lccn/sn83045782/1917-06-03/ed-1/se...

Thanks for your research Art Siegel. We'll add some of the information to the record the next time we update.

This charity garden party on May 22, 1917 was a one-off event, not to be confused with the Greenwich Village Fair, which was held repeatedly.
