Moving eyes, trademark completion of portrait: his? (9)
I believe the answer is:
rembrandt
'completion of portrait his?' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'moving eyes trademark' is the wordplay.
I cannot really see how this works, but
'trademark' could be 'brand' (I've seen this before) and 'brand' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for rembrandt that I've seen before include "Dutch seventeenth-century artist" , "Dutch painter, d. 1669" , "old master" , "Dutch painter, 1606-69" , "Influential Dutch artist" .)
