The Plastic Age (1924) is a novel by Percy Marks, which tells the story of co-eds at a fictional college called Sanford. With contents that covered or implied hazing, partying, and "petting", the book sold well enough to be the second best-selling novel of 1924. The following year, it was adapted into a film of the same name, starring Clara Bow.
In 1928, under the title Red Lips, the novel was again adapted into a film. This remake starred Charles "Buddy" Rogers, who had just co-starred with Clara Bow in a different film, Wings, the previous year.
The Plastic Age was last reprinted in 1980, in a series subtitled, Lost American Fiction.
