Artwork for King or Queen (5)
I believe the answer is:
piece
I believe this is a double definition.
'artwork' is the first definition.
(I've seen this before)
'for king or queen' is the second definition.
(I've seen this before)
(Other definitions for piece that I've seen before include "newspaper article" , "man on board" , "Castle, perhaps" , "A part of something" , "Musical composition" .)
