Curator's concern (3)
I believe the answer is:
art
'curator's concern' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for art that I've seen before include "Painting, for instance" , "The works of Alma-Tadema" , "Paintings etc." , "-- Garfunkel, singer" , "Works in a gallery" .)
