Skeleton of a frog, from an old book on osteology

File-size: 9262 x 14870 Pixel. 

From a beautiful old book on anatomy and osteology from 1733, comes this amazing vintage illustration of a frog skeleton.
Granted, since it's not actually described with text in the book, it could also be a toad or another amphibian, but compared to other pictures, to a layman it looks more like a frog.
Here it is photographed, digitally processed and enlarged, so you can print it yourself and use it as poster or in your many projects.
