Etsy has some fun "alternate histories" prints that depict historic events as connected with monsters and aliens. No one really knows what started the Great Chicago Fire on October 8th 1871, but people like origin stories. The first origin story (fabricated by a reporter) was that cow kicked over a lantern. I think this account of alien conflict is more fun, and you can hang it on your wall. Click here for a larger version of the excellent print above.
