The first duo I thought of when coming up with this style, was these two. Mortal enemies, but also two sides of the same coin, they are somehow both separate, and forever joined. This is true not just thematically, but visually as well, contrasting the black of Batman with the white of Joker.
This is a high quality giclee print, in a satin finish, of an original watercolor painting of Batman and The Joker. Image size: 11" x 17", and comes unframed in rolled art tube, with an original signature by me, the artist.
