Some sites attribute this to Koloman Moser, calling it a self portrait. This appears to be incorrect as there seems to be the signature of Orlik in the upper right hand corner.
This is supported by another print by Orlik, whose title does not mention Moser, but which does have the same monogram signature print (see added view below; https://www.artgallery.nsw.gov.au/collection/works/286.1986/). [sh]
