The photogravures in The Stage and Its Stars by Gebbie & Husson Co. approach an intriguing equal balance of photography and engraving, exemplifying the hybridity of the photogravure process.
George Gebbie was a Philadelphia publisher who produced art books with Photogravures printed in the United States from plates made by Goupil in Paris. In 1887, Gebbie, in partnership with Husson, began to produce their own photogravure plates using the Goupil method that they modified for their use. Mr. Husson stated "Without using the same means [as Goupil], but the same basis, we obtain the same results today, and the success of the Goupil process and of ours comes of the strength of the growing copper plate by electricity and the grain— which is not obtained by any other biting acid." The electrotyping of the printing plate took between 15 and 25 days to complete. (Public Ledger, 1888) [1]
