An oversized man labeled “Beef Trust,” with skeleton face, performs a magic trick on a stage by taking “Diseased Livestock” and pushing them through a tube labeled “Packingtown” to produce packaged “Pure Meat Products.” A diminutive man, “The Prof’s Assistant,” wearing a cap labeled “Inspector,” is standing on the stage on the left. Packingtown is a real section Chicago that was the setting for the horrible actions committed in Upton Sinclair’s novel The Jungle, published as a book when this cartoon appeared. Caption: A monstrous and amazing feat of magic.
