"The oratone is a type of hard photograph. The oratone was used extensively by Edward S. Curtis in the early 1900s. Oratones were created by taking a glass plate coated with gelatin silver emulsion and exposing it to a negative. After the plate is exposed and developed, the back of the plate is painted gold, creating a positive image. The oratone was most popular from the 1890s through the 1920s."USUALLY SHIPS WITHIN 24 HOURS OF RECEIPT OF PAYPAL PAYMENT, VIA STANDARD SHIPPING.
