The organic shapes, each with oval openings, resemble two human pelvis bones, positioned as if copulating.

The work may have a distant relationship to his 1934 sculpture Two Forms (LH 153) in pynkado wood, now held by the Museum of Modern Art in New York.

Moore made a small 16.5 cm (6.5 in) plaster maquette of the work that became Large Two Forms in 1966.

There were also unique versions in plaster and fibreglass, the latter created to be more mobile for exhibition, for example in 1971 at the Belvedere in Florence and the Tuileries Garden in Paris.
