A few years ago, I purchased these two original pen and ink sketches made by Paul Sharp in about 1963.  They were made in preparation for a drawing that appeared in the Follies volume of the National Benzole Books series published in 1963. The final drawing and text appear below. 

Paul Sharp was born in Sowerby Bridge, West Yorkshire in 1912.  He studied at the Royal College of Art, between 1946 and 1949. He died in 1998. "His distinctive, well-ordered graphic style developed into a personal trademark, his work always demonstrating a formal sense of proportion, careful use of white space and preference for sans serif typefaces. His style illustrates the continuing impact of Bauhaus on mid-twentieth century British design." Source: sulisfineart.com
