Artist’s photo like that will do (7)
I believe the answer is:
picasso
'artist's' is the definition.
(Picasso is an example)
'photo like that will do' is the wordplay.
'photo' becomes 'pic' (short for picture).
'like' becomes 'as'.
'that will do' becomes 'so' (I can't explain this - if you can you should believe this answer much more).
'pic'+'as'+'so'='PICASSO'
Can you help me to learn more?
(Other definitions for picasso that I've seen before include "Pablo, great Spanish painter" , "Spanish painter and sculptor" , "Pablo ,,,,,,,, great late Spanish artist" , "So aspic is out for the Spanish artist" , "Pablo . . . . . . ., great Spanish artist of 20th century" .)
