Hank's an artist! (4)

I believe the answer is:
hals
This clue could be a double definition.
'hank's' is the first definition.
Both the answer and definition are singular nouns.
Maybe you can see an association between them that I don't see?
'artist' is the second definition.
(I've seen this before)
'an' acts as a link.
Can you help me to learn more?
(Other definitions for hals that I've seen before include "Frans --, Dutch artist" , "portrait painter" , "Royal portraitist" , "Frans - , Dutch painter (The Laughing Cavalier)" , "Sixteenth to seventeenth century Dutch artist known for portraits" .)
