backdrop

Sorry if this has been discussed or asked before and sorry if I'm posting in the wrong thread, but has Moz ever used this image of Robert Mitchum as a backdrop? If so, when was it, please? Thanks in advance.

Any ideas? Did Moz refer to it ? Fed up with cigarred sailor and later the silver curtain? My presumption so far is (a private pic of) Klaus Nomi sans make-up. What do you think?

What are backdrops and what is backdrops design? What equipment they use to print any backdrops?
