Here are two precursors to
Citizen Kane. The first caption reads, "'Who is Rosebud?' he asked" ("A Treacherous Calm" by Thomas Keyworth, in
Cassells, 1887). The second caption reads, "It was only when he had opened the door that he realized what he had lost in his broken Rosebud" (
Thrilling Life Stories for the Masses, 1892).
