A comics artist (also comic book artist or graphic novel artist, comic book producer, comic book illustrator, comic book writer, and comic book author) is a person working within the comics medium on comic strips, comic books, or graphic novels. The term may refer to any number of artists who contribute to produce a work in the comics form, from those who oversee all aspects of the work to those who contribute only a part.
Within the comic strip format, it is typical for one creator to produce the whole strip. However, it is also not uncommon for the writing of the strip and the drawing of the art to be carried out by two different people, a writer and an artist (with or without additional assistant artists). In some cases, one artist might draw key figures while another does only backgrounds.
Many strips were the work of two people although only one signature was displayed. Shortly after Frank Willard began Moon Mullins in 1923, he hired Ferd Johnson as his assistant. For decades, Johnson received no credit. Willard and Johnson traveled about Florida, Maine, Los Angeles and Mexico, drawing the strip while living in hotels, apartments and farmhouses. At its peak of popularity during the 1940s and 1950s, the strip ran in 350 newspapers. According to Johnson, he had been doing the strip solo for at least a decade before Willard's death in 1958: "They put my name on it then. I had been doing it about 10 years before that because Willard had heart attacks and strokes and all that stuff. The minute my name went on that thing and his name went off, 25 papers dropped the strip. That shows you that, although I had been doing it ten years, the name means a lot."
With regards to the comic book format, the work can be split in many different ways. The writing and the creation of the art can be split between two people, an example being From Hell, which was written by Alan Moore and drawn by Eddie Campbell. The writing of a comic book story can sometimes be shared between two people, with one person writing the plot and another the script.
