Bill of relatively small price, we hear, for picture (7)
I believe the answer is:
tableau
'for picture' is the definition.
(a tableau is a picture or display)
'bill of relatively small price we hear' is the wordplay.
I cannot really understand how this works, but
'bill' could be 'tab' (a tab is a bill at a bar) and 'tab' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for tableau that I've seen before include "Dramatic scene (where the action is frozen?)" , "Dramatic scene - spectacle" , "Figures making a scene" , "A scene with silent motionless group of people" , "Picture of group or scene" .)
