Stand for a holdup in picture production (5)
I believe the answer is:
easel
'stand' is the definition.
(easel is a kind of stand)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for easel that I've seen before include "stand for creativity" , "Painter's frame" , "the rest of the paintwork" , "Tripod for an artist" , "Framework to hold a canvas" .)
