from what I learned about ab!.exp!., this is not it, but if you wiki the artist name, he is considered the grandfather of pop art, so I would go with that, along with the use of line and color, this is definetly a pop art piece!.
as for elements I would say line and color, then movement and proportion for design!.Www@QuestionHome@Com
