A canvas support? (5)

I believe the answer is:

easel

I believe this clue is a double definition.

'a canvas' is the first definition.
(thesaurus)

'support?' is the second definition.
(easel is a kind of support)

(Other definitions for easel that I've seen before include "Lease (anag)" , "Three-legged supporting frame" , "Artistic support" , "Artist's prop" , "Painter's support" .)

I've seen this clue in the Evening Standard.
