Blackstone, Harry (Henry Boughton). Fredrik the Great and Blackstone broadsides. American, 1919. Small pictorial broadsides (6 ¼ x 19”) advertising the “all star company” of both Fredrik the Great and Blackstone – who were one and the same person. Linen backed; Blackstone broadside with some restoration. A-/B+. The text, images, and design of each of these broadsides are identical, save one element: the name of the magician. The earlier piece uses the name “Fredrik the Great,” and the later, “Blackstone.” Harry Blackstone (1885-1965) used the Fredrik the Great stage name for a time, until anti-German sentiment during WWI made him think better of it. He changed his name to Blackstone, and rose to fame as American’s most popular illusionist. These broadsides show the quick transition he made from one name to the other.
