Put one's name on placard (4)

Ross

I believe the answer is:

sign

I believe this clue is a double definition.

'put one's name on' is the first definition.

'placard' is the second definition.
(thesaurus)

(Other definitions for sign that I've seen before include "Evidence" , "Public display of a message" , "Autograph" , "Ram" , "Omen or indication" .)

I've seen this clue in The Guardian.
