A request by the architect Berthold Lubetkin for a sculpture to be placed in an alcove on a block of flats in Hampstead (described in the Introduction to Volume 2 of the catalogue raisonné of drawings) led to Moore's experimenting with upright forms for the alcove sculpture; see also HMF 1392b, 1397, 1394, 1400, 1497. Five of the sketches on the verso are elaborated in HMF 1378. In later years he often said that the upright form allowed the least inventiveness in a pose: he soon abandoned the idea with regard to the Lubetkin proposal and by spring 1938 had begun to carve the Reclining Figure elmwood (LH 210).
