Pretty fine work of art (8)
I believe the answer is:
fetching
'pretty' is the definition.
(thesaurus)
'fine work of art' is the wordplay.
'fine' becomes 'f' (abbreviation).
'work of art' becomes 'etching' (I've seen this before).
'f'+'etching'='FETCHING'
(Other definitions for fetching that I've seen before include "Pretty" , "Going and bringing back" , "a delight" , "collection" , "charming" .)
