Disbanded sketchbook of cream medium-weight wove paper 292 x 242mm to which 40 drawings have been ascribed. Little is known about this sketchbook; it was unnumbered, appears to have been taken apart at an early date, and many of its pages were cut down. In content the drawings are similar to those found in the Unesco Notebook 1954-57 and Heads, Figures and Ideas Sketchbook 1956, but none was reproduced in Heads, Figures and Ideas 1958. Fifteen pages from the mid-1950s which cannot be attributed to any particular sketchbook have been placed at the end of this 1954-56 sequence.
