Erik, the shot of Boris with the Frankie head was taken in the Universal prop dept. in the early 1960's, possibly as publicity for the Thriller TV show. If you look at the head closely, it's not Boris but Glenn Strange, probably from A&C Meet Frankenstein. It's a whole head casting; there are other photos from this session that show the head sitting on a table and you can see more of it.
The shot of Boris being made up as the monster is from the Route 66 Halloween episode "Lizard's Tale and Owlet's Wing". That episode also featured Peter Lorre and Lon Chaney as not only the Wolfman, but as Quasimodo and The Mummy.
