Chicago: The Cherryburn Press 1973. First editions. One of 20 numbered copies signed by Middleton (the entire edition). Middleton's stated objective of this project was to "discover recognizable material, usually in the form of birds, animals, fish, flowers and human profiles, appearing in plausible environments" by "spotting several blobs of water color paint, in different hues" on pieces of heavy tracing paper and then "subject[ing] the paper to quick horizontal movement in several directions." The process was repeated one or more times. "The result will be a mass of crisscrossing irregular width lines and solid shapes, complex in the center but more open in the outer area of the paper." Robert Hunter Middleton (1898-1985) was born near Glasgow and emigrated to Alabama at the age of ten where his father managed a coal mine. He studied painting at the School of the Art Institute of Chicago, and in 1923 began designing typefaces for the Ludlow Typograph Company. There he worked with Ernst F. Detterer and became well known for his Eusebius italic family of typefaces. In 1933, Middleton became art director of the Ludlow Typograph Company and in 1944 he founded the private Cherryburn Press. 2 volumes, folios, 20 linoleum-block prints in colors on Japanese paper, each tipped to a plain paper mat (numbered by hand in Roman), loose as issued. Each volume is accompanied by a title-leaf and 2 leaves of text laid loose in an unprinted paper folder which is itself enclosed in a printed Japanese paper portfolio and publisher's linen and paper over boards ribbon-tied tray case with printed paper spine and front cover labels. Very fine copy in which the tray cases show some light wear (two pair of ribbon ties, of four, perished).
