Jokes became the complete subject of his prints, set atop monochromatic backgrounds red, orange, blue, yellow, etc. These works range in size from 56 × 48 inches as seen in his 1994 "Untitled", to 112 × 203.5 inches, as seen in his 2000 work "Nuts". His early jokes were modestly sized, but as they caught on he executed larger pieces. These Monochromatic Jokes question the importance of the unique, in high art. What is it that set these jokes apart from one another, the background color, the color of the text, the jokes themselves? Compared to other Appropriation Artists working in the same time period, Prince has a distinct quality between works and series. Works are distinguishable from one another or identifiable as a particular artist, but with Prince's Monochromatic Jokes, we are presented with yellow text upon a blue background as in his 1989 "Are You Kidding?" Differing from Jeff Koons, for example, are not only technique and style, but also the significance given to making the artwork identifiable. In 1988 Koons was working with porcelain sculptures like his Michael Jackson and Bubbles and Pink Panther. These are two works produced in this year that are distinguishable. In the same year, 1988, are Prince's "Fireman and the Drunk" and his "Untitled (Joke)", which raise the serious question of what sets these two works apart. In a 2000 interview with Julie L. Belcove, Prince called the joke paintings "what I wanted to become known for." When asked to identify the artistic genre of his Jokes, Prince responded, "the Joke paintings are abstract. Especially in Europe, if you can't speak English."
