Brief evocative description (8)
I believe the answer is:
vignette
'brief evocative description' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for vignette that I've seen before include "Photographic portrait" , "Evocative picture" , "Small illustration at the beginning or end of a book" , "Small illustration, sketch" , "Short description or character sketch" .)
