Figures found at art exhibits (4)
I believe the answer is:
data
'figures' is the definition.
(I've seen this before)
'found at art exhibits' is the wordplay.
'exhibits' says the answer is hidden in the clue.
'DATA' can be found hidden inside 'found at art'.
(Other definitions for data that I've seen before include "intelligence" , "Known facts" , "Contents of some banks?" , "Gathered stats" , "Pieces of information" .)
