From the Emanu-El Newspaper, 17 December 1897, page 16:
"One of the pleasantest entertainments ever given in San Francisco was that given one evening last week by Mr. and Mrs. D. N. Walter at their home, 1700 Van Ness avenue. It was complimentary to Miss Clara Hellman, daughter of Mr. and Mrs. I. W. Hellman, and the invitations asked a hundred and more friends to meet the young guest of honor "at a gathering of the gypsies." Following the plan of the hostess, Miss Mary Bates carried it out in most picturesque detail. The handsome dining-room of the Walter mansion was converted into a gypsy camp. There were tents of skins and canvas, the tripod with the kettle and all sorts of things that go to make up the typical settlement of the Romanies. the other rooms were canvased for dancing and appropriately decorated. Miss Hellman was not with Mrs. Walter to greet the guests, but made her appearance in a beautiful tableau surrounded by a dozen young ladies like herself in gorgeous gypsy garb, she being the queen. After this pretty general introduction she received "in camp," graciously dispensing its hospitality. Interest was added to this scene by the presence of "real" gypsies from a camp on the outskirts. They told past, present and future to the great amusement of the young people. Dice were shaken for prizes. An Italian supper prepared by a chef of that nationality was served before midnight, after which dancing was resumed."
Well what do you think about that? Over 100 teenagers, tents made of animal skins and real gypsies. I love this stuff!
