Sketchbook pages were Moore's library of forms which he used much as Renaissance artists had done. See also  comment on HMF 1337. The third sketch down in the left-hand column reappears with slight variations in HMF 1452 as the foreground figure at centre left, having already been included as a small sketch in HMF 1451. It is also interesting to refer to HMF 1310 where the reclining figure third from the top in the right-hand column is echoed in the third figure down at the extreme right of this drawing.
