The Puppet Master paintings?

In The Puppet Master 2 or 3, maybe 4, there are a few different paintings laying around of what looks to be a Plague Doctor with a big grin on a black background. Oil based maybe. I fell in love with them the first time i watched the movies, but have not been able to find them anywhere. A name of the paintings or artist would be great, but info to a site that sells these paintings or re-makes would be amazing.... MCL
