Well-recognized (6)
I believe the answer is:
iconic
'well-recognized' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for iconic that I've seen before include "Serving as a significant symbol" , "(Of paintings/statues) in a fixed conventional style" , "Symbolically representative" , "famously representative" , "Well-known and representative of a particular idea" .)
