Publicity material after the passing of the Queen? (6)
I believe the answer is:
poster
'publicity material' is the definition.
'after the passing of the queen?' is the wordplay.
I cannot quite understand how this works, but
'after' could be 'post' (prefix meaning after, eg post-war) and 'post' is found within the answer.
'queen?' could be 'er' (short for Elizabeth Regina ie Queen Elizabeth) and 'er' is found within the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for poster that I've seen before include "Large printed bill" , "'Notice, placard (6)'" , "bulletin board participant" , "Bill or placard" , "Town near Glasgow" .)
