A salver of arty design (4)
I believe the answer is:
tray
'a salver' is the definition.
(I've seen this in another clue)
'arty design' is the wordplay.
'design' indicates an anagram.
'arty' with letters rearranged gives 'TRAY'.
'of' is the link.
(Other definitions for tray that I've seen before include "Salver" , "Item used for carrying food and drink" , "platter" , "Flat board for carrying things" , "Kitchen carrier" .)
