There's a fairly good pic in one of the Lucky Luke comic books (vol 31, at the end of the book)
And on this German site:http://rooschristoph.blogspot.de/2012/06/roy-bean.html
And you'll perhaps find a few new ones by googling in German: http://www.google.de/search?q=Roy+be...w=1280&bih=879
What about Rick? Doesn't he participate? There are quite a few celebs we didn't cover yet: Pocahontas (though being pacifist and from the East coast she might not count), Big Nose Kate, Billie the Kid, Butch Cassidy & Sundance Kid, Black Bart the rhyming robber, the Dalton Gang, Buckshot rogers, Johnny Ringo etc.
Then there was that woman who lived as a trapper and they found out her gender only when she had died - I can't recall her name.
And how about the real and fake Native Americans? Grey Owl (fake), Tecumseh (genuine), Seattle (prophetic) etc?
And since we have Sitting Bull, how about Custer? Davy Crockett? Daniel Boone?
