Art deco pieces entertaining camper (7)
I believe the answer is:
redcoat
'entertaining camper' is the definition.
(entertainer at Butlin's holiday centres)
'art deco pieces' is the wordplay.
'pieces' is an anagram indicator (the same pieces in a new order).
'art'+'deco'='artdeco'
'artdeco' anagrammed gives 'REDCOAT'.
(Other definitions for redcoat that I've seen before include "British soldier (hist.)" , "camp entertainer" , "Do react (anag) - old soldier" , "British soldier in the American War of Independence" , "British soldier or Butlin's worker" .)
