FREDRIK, Alexander. Fredrik the Great. American, ca. 1915. Two-color offset poster for the American magician bearing a bust portrait of the performer in white tie and jacket, framed by an oval border in red, the balance of the sheet filled with bats, playing cards, and demons, and with the original date tag affixed below. 28 ? x 20 ?? (poster only). Old folds small losses in upper left. Date tag brittle and split at center. Uncommon. In the late ?teens, Henry Boughton purchased the advertising material left behind at the end of Frederik?s career and assumed his name, performing on stages across America as Frederik. But as anti-German sentiment from WWI rose, Boughton found the association too much to bear, and in 1919 changed his stage name to one that would be with him for the rest of his days: Harry Blackstone. This uncommon poster is from those pre-Blackstone days and is one of only three we have encountered.
