Key belonging to woman artist (6)

I believe the answer is:

escher

'artist' is the definition.
(I've seen this before)

'key belonging to woman' is the wordplay.
'key' becomes 'esc' ('Escape' key on a computer keyboard).
'belonging to woman' becomes 'her'.
'esc'+'her'='ESCHER'

(Another definition for escher that I've seen is " M. C. --, Dutch graphic artist".)

I've seen this clue in The Irish Times.
