The gently curving bone shapes on the recto are in stark contrast to the spiky geometrical shapes on the verso which may belong to a later date, possibly as late as 1934. The sketches lower right on the recto appear to be connected with abstract compositions of 1934 such as LH 140 and LH 154, whereas the sketch on the left of the second line is linked to Composition 1933 (LH 132).
