Carnival in the Clothes Cupboard (1941)

A colorful cartoon commercial for soap flakes seems the last place that the realities of wartime life should creep in. A clothes cupboard opens to reveal a fantasy world where figures on fabric patterns come to life, and a neglected clown is shunned until he bathes in Lux Flakes. But in a last-minute coda, the clown returns to break the animated fourth wall and tell the audience that the product will not be made again till the war is over.
