Spooner's Labrador's little toe is quite a picture (7)
I believe the answer is:
tableau
'picture' is the definition.
(a tableau is a picture or display)
'spooner's labrador's little toe is quite a' is the wordplay.
I cannot really see how this works, but
'little' could be 'l' (abbreviation) and 'l' is present in the answer.
'is' could be 'be' and 'be' is located in the leftover letters.
'a' is within the answer.
The remaining letters 'tau' is a valid word which might be clued in a way I don't see.
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 - spectacle" , "Frozen stage scene" , "Scene represented by motionless figures" , "Group of models representing a scene" , "picture that's striking" .)
