1930's war anime --

"Toy Box Series, Episode 3: Picture Book 1936" (Omocha-Bako Series, Dai-3-Wa: Ehon 1936) is a 1934 propaganda-ish film about a future (1936) conflict started by a swarm of evil, bat-riding Mickey Mouse clones that descend on a tiny island inhabited by peace-loving dolls and cats (including a Felix lookalike). Overwhelmed by the attack, the desperate island residents bang on the cover of a large picture book to enlist the help of Momotaro, Urashima Taro (the Japanese version of Rip Van Winkle), and other traditional fairy tale heroes and characters. After Urashima Taro uses his famous "mystery box" to turn the big Mickey into a decrepit old fogey, Hanasaka Jiisan makes the cherry trees bloom and the cats and dolls celebrate by dancing to "Tokyo Ondo" (an old Japanese folk song). The soundtrack also includes renditions of the Momotaro song and Gunkan March ("Warship March"), a song that is nowadays typically played at pachinko parlors.
