Subscription needed by such a hunter? (9)
I believe the answer is:
autograph
'subscription' is the definition.
(thesaurus)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for autograph that I've seen before include "Sign" , "(Celebrity's) signature" , "One's signed" , "A signature given as souvenir" , "One's signature" .)
