I saw an HBO doc about the exhumation of his body years ago and I think I remember hearing something about his casket being lined with lead, and this being a very big factor in how well his body was preserved. Guess the bugs and elements couldn't get in...Also, there was pic on that of Evers' son as a grown man looking at his father's body - the son was the same age as Evers when he died...it was like looking in a mirror. Wish I could find it to post...

That'd be super chilling. The preservation was quite amazing.
