These are test make-up shots of Boris Karloff in "The Old Dark House". Jack Pierce did the make-up. The final result was more subtile and less terrifying.
This is a rare behind the scenes photo of Lon Chaney getting his make-up applied in "Abbott and Costello Meet Frankenstein". This Wolf Man make-up was not done by Jack Pierce, but by Bud Westmore. The results were not nearly as good as Pierce's version.
