Douglas Darden laughter was the laughter of three young girls, who were, in essence, their clients: the fourteen year-old twins, Cass and Polly, and their nineteen-year-old friend, Helen. Cass and Polly are most likely feminized renderings of the celestial twins of Greek mythology, Castor and Pollux (better known as Gemini), and their sister, Helen of Troy. Many of his original sketches and drawings for Oxygen House are now owned by the Museum of Modern Art, along with a select few of "Sex Shop" drawings; gifts of Darden's widow. The remainder of his drawings are held at the Avery Architectural and Fine Arts
Castor and Pollux (Prado) into the Prado (catalogue number Catalogue Nr. E.28). The erroneous identification with Antinous generated high interest in the sculpture, with large numbers of copies being produced, largely made in Italy and Northern Europe and based on plaster casts rather than made in Spain and based on the original there. These inevitably stoked the interest by obscuring the fact that the Antinous head was in fact a restoration, instead smoothing the two into a meaningful whole (as did the casts on which they were based).
