Item usually containing a photograph of one dead Queen? (2,4)
I believe the answer is:
id card
'item usually containing a photograph' is the definition.
I know nothing about this answer so I can't judge whether this works.
'one dead queen?' is the wordplay.
'one' becomes 'i' (Roman numeral).
'dead' becomes 'd' (abbreviation in government records).
'queen?' becomes 'card' (queen is a kind of playing card).
'i'+'d'+'card'='ID CARD'
'of' acts as a link.
Can you help me to learn more?
(Other definitions for id card that I've seen before include "Proof of personal details" , "It says who the bearer is" , "Identification document" .)
