These elephant costume accessory hats are a blast...It's like wearing Dumbo on your head! Who's that? Dumbo is a 1941 American animated feature produced by Walt Disney based upon a child's book of the same name by Helen Aberson and illustrated by Harold Perl. The main character is Jumbo Jr., a semi-anthropomorphic elephant who is cruelly nicknamed Dumbo. He is ridiculed for his big ears, but in fact he is capable of flying by using his ears as wings.
