Ambiguous Images

The essay I received back was mostly taken from wikipeadia. Id like you to write an essay on ambiguous images and explain the example pictures below on the last two pages.
Begin the paper presentation by definingxand discussing your topic, and providing a brief history. You will then discuss and analyze each image you have selected and its relationship to your topics.
