Thank you for your appraisal inquiry with MeArto. The print appears to be a photomechanical reproduction after a painting by Edwin Longsden Long, RA (English, 1829 - 1891) titled "Diana or Christ." The original painting was produced in 1881 and is now held in the collection of Blackburn Museum and Art Gallery, England. Long was one of the best known Orientalist artist of the late 19th century.

The print here is most likely a photogravure, which combines photography and intaglio printing methods to produce a quality reproduction print. The most available photogravure of this print was published by Gebbie and Husson Co., Philadelphia. This information would be noted to the lower left margin. However, I am not able to see the information from the photo uploaded here. The estimate provided is based on recent auction estimates and results of Gebbie and Husson Co. photogravure prints after Edwin Long paintings.
