Artist finding pig painting, for example, hard (7)
I believe the answer is:
hogarth
'artist' is the definition.
(I've seen this before)
'pig painting for example hard' is the wordplay.
'pig' becomes 'hog' ('hog' can be a synonym of 'pig').
'painting for example' becomes 'art' (painting is a kind of art).
'hard' becomes 'h'.
'hog'+'art'+'h'='HOGARTH'
'finding' is the link.
(Other definitions for hogarth that I've seen before include "William ---, Brit. artist" , "English painter and satirist, d. 1764" , "William -, Eng. engraver (A Rake's Progress)" , "Satirical 18th century painter" , "William --, painter and satirist" .)
