(Thought Factory, 1977) An extremely rare original painting of the classic Marvel Comics superhero "Spider-Man". Painted by the incredible Ron Kriss, the artwork features a more realistic depiction of the character at top, and a more traditional comic-panel style representation at the bottom. This original artwork was created and used in a popular series of collectible posters that were marketed by a partnership between Thought Factory and Bill Wallen, and comes from Wallen's personal collection. The artwork is composed of primarily airbrush, with the comic-panel artwork at the bottom hand-colored in either marker or diluted paints for a more comic book feel. The "Ron Kriss" logo and the comic-panel artwork at the bottom were both created on separate sheets, then trimmed and applied over the larger artwork. Measuring 37.25"x26.25" on sturdy art board, the original painting is in very good condition with minor expected wear from the production process including some scuffs in the margins and some lifting to the comic-panel artwork from the board. The Thought Factory superhero posters were very popular when they debuted in 1977, with surviving examples becoming difficult to find. This is the first time the original artwork for these exceptional posters has ever been offered for public sale, and beautifully represents the legacy of this iconic superhero.
