Resin tablet produced by Ken Williams, supervisor of the 1971 excavations.
About the tablet:
“The Birdman tablet was discovered in 1971, during excavations at the base of the eastern side of Monks Mound, conducted by the University of Wisconsin at Milwaukee. This is an extremely accurate facsimile, produced from a second generation mold of the original sandstone artifact.
Archaeologist theorize that the bird of prey on the front of the tablet symbolically represents the Upper World. The Middle World (of man) is represented by the human figure wearing the costume, and the Lower World is represented by the snake skin pattern found on the back of the tablet.”
