2013-07-05 Piasa Bird
You can look this up for yourself, but basically the Piasa Bird painting you see here is a reproduction based on a written depiction of a Native American painting seen over 300 years ago by French explorers.
The name means "the bird that devours men" - basically a Native American monster. Pretty great.
It's painted on limestone bluffs on the banks of the Mississippi, near where it was first seen.
