Humorous drawing (7)
I believe the answer is:
cartoon
'humorous drawing' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for cartoon that I've seen before include "One may find it funny" , "Humorous sketch" , "Humorous drawing or film of a succession of them" , "Comical drawing" , "Animated film made by photographing a series of drawings" .)
