Me too Martin. When a driver ploughed into the back of me a few years back the young PC who attended asked to see my licence. When I handed it to him he said, "this is old" and I replied, "so am I". I suspect he'd never seen one before.
Had to get a new one due to moving house.
I had photos ready thinking I'd have to post the form to the DVLA, but like Keith I had an old one with no photo and it was straight forward doing it online.
