This document summarizes and provides context for four famous American paintings: Gilbert Stuart's unfinished portrait of George Washington, Andy Warhol's portrait of Marilyn Monroe, Grant Wood's "American Gothic", and Jasper Johns' "Three Flags". It notes that Stuart left his portrait of the first US President unfinished; that Warhol was known for his colorful pop art style and portraits of celebrities; that "American Gothic" depicts a couple on a farm based on people the artist imagined; and that "Three Flags" from 1958 features 48 stars on the flag to represent states at that time.
