A while back I posted a recently acquired original publicity photo for the 1903 Broadway production of The Wizard of Oz, featuring Fred Stone and Dave Montgomery as the Scarecrow and Tin Man, with the Tin Man using a pistol to hold a stuffed bear at bay.
This picture was part of a 1911 article by Fred Stone, published in the Hampton Columbian magazine. The story was titled The Scarecrow's Polar Bear Hunt, and details a trip taken by Fred to the Arctic in order to hunt polar bears. Of course Fred didn't actually travel in his Scarecrow character, it was a straight-forward big game hunt. Although the story is written with a humorous edge, the actual hunt sounds rather brutal and repulsive to my taste - the full article can be read here.
Incidentally, on the subject of the Scarecrow and guns - don't forget that in the 1939 MGM film, the Scarecrow carries a revolver with him when heading to search for the Wicked Witch of the West!
