Letter-card (9)
I believe the answer is:
character
I believe this clue is a double definition.
'letter' is the first definition.
(I've seen this before)
'card' is the second definition.
(thesaurus)
(Other definitions for character that I've seen before include "Make-up" , "Letter or figure" , "crank" , "Someone in play" , "Stamp < letter" .)
