ONE property developer wanted to have a little joke in their advertisements to the commuters of Oxford in 1992.

The developers behind a new site Farmoor Court decided to highlight to the many drivers on Botley Road that just two miles away they could enjoy the clean-aired village of Farmoor.

Developers installed this sign in July that year to sit alongside the daily congestion which has long plagued Botley Road.

It proudly displayed the words 'Welcome to Carbon MonOxford' as a play on words about the city's pollution and in a bid to entice house hunters.

The suggestion appeared to encourage people to take up the offer and buy a home in Farmoor away from the city's carbon monoxide gases.

Below the sign said in small print 'Breathe fresh life into your business, relocate to Farmoor Court' and contact details.
