Violet Press, 1977. Distributed by Light Impressions. Violet quarto wraps, 30 pages, stapled. 1st ed., VG+ with minor evidence of handling, including crimps on the thin cover. No fading or foxing as common with this title. Has been stored in a zip lock bag since acquisition in 2003.  Includes formulas and procedures.
