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 lastminute 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
