Our country would look pretty different if it weren’t for the defeat of General Frankenstein at Bunker Hill or Metallo the mechanical man’s passages in the Declaration of Independence. At least thats the way these events occur in artist Matthew Buchholz’s ‘Alternate Histories’ poster series.

The re-imaginings depict memorable historical events with a dash of sci-fi-inspired invasions from sea monsters, menacing aliens, hulking robots and roaming dinosaurs.
