Box where sculpture perhaps hidden in deception (6)
I believe the answer is:
carton
'box' is the definition.
(I know that carton is a type of box)
'sculpture perhaps hidden in deception' is the wordplay.
'sculpture perhaps' becomes 'art' (sculpture is a kind of art).
'hidden in' indicates putting letters inside.
'deception' becomes 'con' (a con is a trick or deception).
'art' put into 'con' is 'CARTON'.
'where' is the link.
(Other definitions for carton that I've seen before include "He did a far, far better thing" , "Sydney -, Tale of Two Cities hero" , "Dickensian hero" , "Flapped cardboard box" , "Light cardboard box" .)
