AMUSEMENT NEWS-Brooklyn NEWS-Brooklyn NEWS-Brooklyn is responsible for one of the most-patronized most-patronized most-patronized amusements In Rio de Janeiro. It's the whip, well known as a thrill feature at Coney Island. William F. Mangels, Mangels, quiet inventor of the contraption and of most Luna Park gadgets, has his factory right In Coney Island, other day learned all about the popularity of his Invention down in South America. He was poking about his office, thinking vaguely of new amusement Inventions, when a very vital lady burst In, said she was Mrs. Shaw. He couldnt place her until she reminded him he'd sold her two whips years ago. She'd come In to get some spare parts, and to negotiate about purchase of other amusement devices. Said Rio is developing a regular Coney Island of its own. And she had a new idea. She wondered why it wouldn't pay for amusement people to have life-sized life-sized life-sized models of movie stars, so that they could go to a dance-hall dance-hall dance-hall and have, say, Greta, Garbo or Clark Gable as a floor-partner. floor-partner. floor-partner. The models would be fitted to moving disks, so that they'd follow steps perfectly. Mangels told the lady the idea was swell except that it wouldn't work for the reason that too many youths would deface them, put mustaches on Greta Garbo, a woman's hat on Clark Gable.
