Plate 573 envelope, Acoma Water Girls Curtis, Edward Sherrif  (American, 1868-1952)

This "plate envelope" or "plate cover", was handmade to house their respective copper photogravure plates for protection and identification, and as such are unique. Each envelope has a proof print attached to the front and notations as to the title, copyright date, printing notes, the date of printing, etc. There are also thumb prints of the printer’s themselves, and other evidence of the printing process. Plate envelopes are a very important form of Curtis ephemera as they are a key early document relating to the creation of Curtis’ magnum opus, The North American Indian.
