"A l'Heure de l'Observatoire - Les Amoureux" is considered to be one of Man Ray’s most iconic images.
The lips featured in the composition are those of Man Ray’s photography assistant and lover, Lee Miller.
Her lips appear as a motif in a range of Man Ray’s work from throughout his lifetime, from a photograph in MoMA’s collection from 1929, to a major series of paintings in 1936, and even a cast-gold version.
They have gone on to inspire a number of images in pop culture, most famously the iconic lips from the movie The Rocky Horror Picture Show.
