(*) Even though this photo is uncredited (and undated) on source (Theatermuseum Wien), note that the image bears a blindstamp with the date (1904) with the same typography as the third photo in this post and in the same place (lower left). Furthermore, the dance costume and hairstyle in the “anonymous” photo is just the same as in the image found in Alamy (second image of the post); that said, it is highly probable that the maker of this image is also Atelier / Hof-Atelier Elvira.
