This is an 1897 woodcut printing block used for publication of a newspaper [haven't figured out which one yet] showing Jim Corbett and Bob Fitzsimmons, who fought for the heavyweight title.  Note the names are backwards on the block--it was a direct transfer print [ink goes on the surface then right onto the paper].  The wood is hardwood and the printing surface is heavily crazed from the chemicals used to create the print.
