if nothing else, i saw some cool-ass CFTBL-type art googling this...no luck with your pic though
JOHN PETIK "Christ promised the resurrection of the dead. I just thought he had something a little different in mind." http://s1294.beta.photobucket.com/
I also came up completely empty on Google... but another friend on FB revealed that these two were background characters on a Krofft special, "Krofft Supershow". Figures!
Mystery solved!
Many years ago a episode or pilot for a series , possibly on sci fi channel had creatures much like this without clothing as an ante-deluvian race of reptile men who were hatching from ancient eggs.
In the "Special unit 2" series they had some similar fishmen.
I suspect availability of good quality CFBL masks made the general appearance attractive for monsters in lower budget productions.
