Artist's equipment from eastern jumble sale (5)
I believe the answer is:
easel
'artist's equipment' is the definition.
(I've seen this before)
'eastern jumble sale' is the wordplay.
'eastern' becomes 'e' ().
'jumble' indicates anagramming the letters.
'sale' is an anagram of 'asel'.
'e'+'asel'='EASEL'
'from' is the link.
(Other definitions for easel that I've seen before include "Constable's stand?" , "Painter's stand" , "art supporter" , "Van Gogh's stand?" , "Board stanchion" .)
