Cool Posters are 18 x 24 inches.  Pretty darn big.

This beautiful poster is accurate and to scale, it is original artwork created from an actual Australopithecus africanus skull.  I really like the front view and the side together and I hope you do also.

Fun Fact:  This australopith got it's name because it was misidentified as an example of a Plesianthropus transvaalensis species. The newspaper at the time jumped on that and named her Mrs. Ples.

The poster is a great piece of art that will make a statement in any room. It is a matte, museum-quality poster printed sweatshop-free in the USA on durable, archival paper.
