I came across this series of posters and thought they were amazing!  They are historically accurate and highlight some of the more bad ass historical figures.  They were created by a two students, Jenny Burrows and Matt Kappler, for a school project.  You can read more about their posters and download them at their WEBSITE.  These posters have been very popular online because they were thought to have been created by the Smithsonian.  While they were not made by any museum, they are still fun!  Enjoy!
