here's an intriguing sign which has many possibly meanings.

* was it written in the 60s when 'cat' was a funky word you appended to any sentence to be cool ? the 'old' referred respectfully to the fact that only rich people could afford cars ?

* are there lots of old cats hobbling around with little catty zimmer frames just round the corner ?

* or is it for cat drivers driving their catty cars ? cats are notoriously fast and unsafe drivers. this is a purr-fect sign for chauf-furs (chauffeurs).
