The photogravure is from a set of eight Persian images by Antoin Sevruguin and was printed by Charles Gillot (1853-1903), a Paris based engraver and art collector who incorporated the photographic discoveries of Daguerre and Niepce into his engraving techniques and ultimately perfected a process for reproducing book illustrations in colour. The image has the number “347” in white ink on recto in the same location as the albumen print of this image in the Nelson collection.
