Page allowed to produce handbill (7)
I believe the answer is:
leaflet
'handbill' is the definition.
(I've seen this before)
'page allowed to' is the wordplay.
'page' becomes 'leaf' (leaf can mean a page).
'allowed to' becomes 'let' (to let something happen is to allow it).
'leaf'+'let'='LEAFLET'
'produce' is the link.
(Other definitions for leaflet that I've seen before include "Brochure" , "Tract" , "Distribute small circulars" , "Distribute information" , "Printed handout" .)
