Henry Moore (1898-1986) was a English sculptor who specialized in works featuring carved heads and abstract human forms, the latter often in a reclining position. As his career progressed, Moore favored very large works, many weighing upwards of 1,000 pounds, and received numerous commissions to create pieces for sculpture gardens and other public spaces. By the late-1940s his body of work was often the 'measuring stick' to which other sculptors compared their work. The statuette (likely a replica) that Tina owns is an actual piece that can be found in catalogs of Moore's work.

Clarke was a British-Irish photographer whose work was heavily involved with nude erotic images, but also included portrait and commercial photography. He was sometimes referred to as the 'British Helmut Newton.' A great deal of his art is held at London's National Portrait Gallery.
