Octavo. 119pp. Part reference guide, part sales vehicle, the Du Pont chemical company here has compiled 54 pages of sample dyed papers, with each page complemented by a facing explanatory statement. Papers represented are kraft, bleached and unbleached sulfite, rag, and 50/50 ground wood and unbleached sulfite. A remarkable demonstration of technical enterprise, with graphic appeal. Bound in quarter brown cloth with paper over boards and gilt titling. Evident but unobtrusive fingerprints to margins of exterior, bumps to corners, else near fine. Laid in is a letter from a Du Pont representative providing further explanation of the chemical composition of the dyes. Bookplate of former owner, to whom the letter is addressed.
