Warhol was captivated by consumerism. Warhol created art from everyday images of consumer goods. Themes in his Ad portfolio include glamour, memories from childhood, celebrities, and even corporate identities. Pop Art was an experimental form of art. Warhol, the "Pope of Pop", turned to this new style, where popular subjects, such as commercial advertisements, could be part of the artist's palette. His early paintings of abstract expressionism showcase advertisements, hand-painted with paint drips. Eventually, Warhol removed the evidence of his artistic "hand" completely.
