Face of Patty Perkins (4)
I believe the answer is:
type
'face' is the definition.
(I have seen 'The face' mean 'type' so perhaps 'face' could also mean 'type')
'of patty perkins' is the wordplay.
'of' indicates a hidden word.
'TYPE' can be found hidden inside 'patty perkins'.
(Other definitions for type that I've seen before include "Figure" , "Sort, variety" , "Kind or class as of people" , "Write letters" , "The face" .)
