The National Police Gazette, New York, N.Y. 12/4/1915
Proofing was rather lax in the past. This is the only mention of Lina Cavalieri mentioned in the entire tabloid (mostly a sporting paper) and it is a photo of Guerrero. There is a great resemblance between the two in early Reutlinger photos.
I've seen contemporary newspaper articles on Guerrero containing photos of the Australian dancer Saharet. In fact, there is a book called Der Tanz, I think published in the 1920s or 1930s, where she is represented by a photograph of Saharet. Saharet, though a can-can dancer, was photographed many times in Spanish costume.
There is one photo postcard of Guerrero, where "Cavalieri" is airbrushed out and "Guerrero" is typed in.
