Greedy type, earthy, stripped off for artist (7)
I believe the answer is:
hogarth
'for artist' is the definition.
(William Hogarth, 1697-1764)
'greedy type earthy stripped off' is the wordplay.
'greedy type' becomes 'hog' (I've seen this in another clue).
'stripped off' says to take the centre (the outer letters are stripped off).
The middle of 'earthy' is 'arth'.
'hog'+'arth'='HOGARTH'
(Other definitions for hogarth that I've seen before include "William ---, Brit. artist" , "William -, eighteenth century English engraver" , "A Rake's Progress artist" , "Engraver's" , "William --, English painter and cartoonist" .)
