This is George Washington modeled by the Italian sculptor, Giuseppe Ceracchi in 1795. For some more info you can check out the METs page https://www.metmuseum.org/art/collection/search/192901. 

This is a 3d scan of the original work from the Smithsonian of which I attribute full credit. I have fixed it up a bit in tinker cad to make it more printable but it does require some supports on the underside but can be done if your bridging settings are good. I printed mine at 50% to save filament but the larger model is much more visually appealing and have included the  gcode file with 0.15 mm layer heights if you don't want to slice it yourself.
