Permits required to see such timeless scenes (5)
I believe the answer is:
visas
'scenes' is the definition.
The definition and answer can be both related to communication as well as being plural nouns.
Maybe you can see a link between them that I can't see?
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for visas that I've seen before include "Travel documents required by some countries" , "More than one travel document" , "They allow the bearer to enter a country" , "They allow bearers to enter a country" , "travel permits" .)
