The old American Lyceum Association, of which Mark Twain was a member,
changed its name to International Platform Association in 1905. Over
the years they have awarded numerous Mark Twain awards including
awards to Jean Shepherd, Norman Lear, Phyllis Diller and others. If
you do a google search on:
"International Platform Association" + "Mark Twain"
you will get a number of hits on other award winners.
