Carl J. Peyfuss (1865-1932) Nude Ephebe 1884

Addendum: I finally identified the artist. He is Carl J. Peyfuss (1865-1932). Please see the additional listing for Biographical information regarding Peyfuss.
-------------------------------
Here's another Austrian drawing that I have been unable to decipher the artist's signature. It is dated 1884 and came from a Seller in Vienna, Austria. I wish I had more information on the artist but unfortunately I have not been able to properly identify him or her. This drawing is highlighted in white chalk which adds greater depth to the figure.
