The resulting bronze bust with arms crossed was displayed at the Leicester Galleries in 1920. Epstein also completed a bronze head of Betty in 1921. It was also at about this time that she sat for Jacob Kramer's "The Sphinx" which had been commissioned from Kramer by a Bradford manufacturer who had met May at the Harlequin Club and been much taken with her. According to May, the sittings took place at the Harlequin as Kramer was too poor to be able to afford a studio. May wrote that Kramer fell in love with her and they became engaged but were prevented from marrying by Kramer's mother who would not let him marry a non-Jew (although his sister Sarah married the non-Jewish painter William Roberts and Roberts and her mother apparently got on well). The painting was exhibited at the 1924/25 British Empire Exhibition at Wembley. The Harlequin Club, at 55 Beak Street, off Regent Street, became a popular haunt of the poorer bohemians around this time. Betty May and her group became regulars. The club was based in the home of Yanni Papani who was also a waiter at the Café Royal. William Roberts remembered in his posthumously published (1990) memoirs the Harlequin's female customers "whose vocal talents turned the place at times into a sort of "Café Chantant", when the dark-skinned Helene sang the 'Raggle-Taggle Gypsies, O!' or Gypsy Lang sang Casey Jones the engine-driver's lament; with the vivacious Betty May, called the Tiger Woman, together with Dolores and the Snake Charmer (so called from her habit of carrying around a small basket of snakes) joining in the chorus." In 1919, "Bunny" Garnett, writing as Leda Burke, published a sensational novel titled "Dope-Darling: A Story of Cocaine" whose central female character "Claire" was loosely based on Betty May whom he knew well. The plot revolves around an idealistic young man "Roy" who is taken to a club near Fleet Street frequented by journalists. There he is enraptured by the singer, a sexually experienced young woman who had arrived in London aged sixteen just two years earlier, was duped into taking drugs and then into a life of prostitution. Roy marries Claire and tries to reform her but instead is drawn into drug use himself. Garnett wrote of Claire: She was always asked to all the parties given in the flashy Bohemian world in which she moved.
