Masterpieces of Frog Art
I stumbled across this weird gallery while looking for works by Christoph Jamnitzer. Frogs have been placed into reinterpretations of works by artists such as Hieronymus Bosch, Pieter Breughel, Alfred Kubin, and many others. Having browsed through most of the pages I feel like I just stepped out of some weird drug induced nightmare.
And I found this page full of many bizarre images of frogs from Myth and Religion.
