Cross about prize, one of many on display in Harley Street? (9)

I believe the answer is:

doorplate

'one of many on display in harley street?' is the definition.
(location of many doctors' offices with doorplates)

'cross about prize' is the wordplay.
'cross' becomes 'rood' (term for a crucifix).
'about' is a reversal indicator.
'prize' becomes 'plate' (a plate may be given as a trophy).
'rood' in reverse letter order is 'door'.
'door'+'plate'='DOORPLATE'

I've seen this clue in The Times.
