The Temple of Dagon

While cruising the interweb for Mythos-related images, I have come across some illustrations done in an old-school engraving style. However, I am not having any luck finding out where there are from, who they are by, or a good source for quality copies. Example is below.

If anyone can help, please let me know as these are perfect for a project that I am working on......

Hmm, this picture was published in the Pen-and-Paper Call of Cthulhu RPG rulebook. I think my edition was the 5th, and it featured this kind of illustrations for many creatures of the mythos.

Yes i have a few copies of the cthluhu RPG books myself and it looks about right
