Here’s a picture from the photo page of the May 6 1929 edition of the Toronto Daily Star of a young woman who was honoured as America’s most beautiful debutante.
Ms. de Acosta went on to appear in some Broadway plays in 1930. (Though Playbill’s entry for her is a bit suspicious, as I doubt that she appeared in two separate plays whose opening night was September 29, 1930. I suppose that it could have been a twin bill.) The New York City Public Library Digital Collections includes a photograph of her in one of these roles.
She married George Trowbridge Elliman in 1931 and passed away in 1989.
