Rather than recap a small bio on Jasper Johns, I recommend the sites listed on the links page, which contain bios and examples of Johns' fantastic Pop artwork.

what is a fanlisting?
as stated on tfl.org, a fanlisting is:
a web clique that lists fans of a particular subject. Unlike most web cliques, a person does not need a website in order to join. Fans from around the world submit their information to their approved fanlisting and they are then listed to show their love for the subject.
