Illustrator Rockwell (6)
I believe the answer is:
norman
'illustrator rockwell' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for norman that I've seen before include "Barry, Greg or Jessye" , "French dialect" , "Style of architecture" , "British comedian, once a cult figure in Albania, d. 2010" , "Black Wednesday's Chancellor of the Exchequer" .)
