Small parts for big names (6)
I believe the answer is:
cameos
'small parts for big names' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for cameos that I've seen before include "Small stones carved with raised designs" , "Came so close to small carvings" , "Small pieces of stone carved with raised designs" , "pieces of jewelry" , "Portraits in profile carved in relief" .)
