Hi William. I have the same original image as of your attachment of the Cabin Camera by Alfred Werner you sent me. I also have another view of the door of the cabin from which you entered the camera..Thank you..
Hi William. I just found some ephemera relating to a large glass negative. Created before "The Worlds Fair Chicargo" in 1893. of where it won a Premier award.. The Photographer was Alfred Werner FRPS of the Photographic Society of Ireland.The image was of Madame Gonne McBride in Dublin.She became famous as a leader of women's rights..The negative size was reported as being 5'6" x 3'2" I belive it is held in The National Gallery of Ireland, both the negative and the contact print.
