I wish this image were in color, it’s a really striking design; the marks are almost sketch-like appearing at random to build a dimensional landscape. Thirstland Treks by Carel Birkby was printed by Faber and Faber in 1936 and this copy was bound by Edgar Mansfield in 1948. Covered in a native dyed yellow-brown morocco skin with slight creasing in the grain. The tooling is a combination of light and dark blind with a small amount of gold on the cover and spine.
This is the first experiment with using the grain as an active and expressive element in the design.
