Over the years Evening News readers have helped to raised more than �15,000 for the Norfolk Deaf Children's Society. Derek James reports.

The postcards you have been kind enough to send my way over the years have now raised the grand total of �15,161.63 for the Norfolk Deaf Children's Society.

'We can't thank your readers enough. They are so generous and, thanks to them, a lot of deaf children in the county have been helped,' said Michael Porter.

I pass all your cards on to the experts, Michael and his wife Sylvia, who sell them to raise money for the society.

They have made tens of thousands of pounds by selling postcards and they supply collectors all over this country and abroad.

Think of a subject and the chances are they will know someone, somewhere, who wants your old card.

Picture postcards are a window on a lost world.

A century ago photographers were out and about capturing the places and people of the day.

They would see something which took their fancy, and out came the camera.

One old postcard was sent in the other day by someone who didn't leave their name.

All it says on the back is that it is the road-tarring gang working at Hoveton about a century ago. They certainly had their five minutes of fame.

The photographer would have snapped them while out and about on his rounds and soon afterwards they could buy a picture of themselves in the shops to send to friends and relatives.

A city view, which was turned into a postcard, was taken in Rosemary Lane about a century ago.

The lane took its name from the old Pykerell House – home to sheriff and mayor Thomas Pykerell.

It became Pilgrim's Hall, which was converted into the Rosemary Tavern.

The view is up to St Mary's Plain towards St Miles' Alley.

Many of the 16th-century properties were pulled down during slum-clearance programmes in the 1930s or blown up in the war. Pykerell's House survived.

Moving forward a few years and we have the floral clock in Great Yarmouth back in 1955 when the resort was at the heart of the booming traditional seaside holiday when everybody was, of course, having a good time.

That dear old clock was a real work of art – a favourite seafront feature at the holiday hot spot...and a reminder of warmer times.

Please keep those cards coming in and thanks to everybody who has sent them in over the last few weeks. There have been some real beauties.

They can be dropped off at Prospect House at the top of Rouen Road or, if you would prefer, give me a ring or drop me an email and I will arrange for them to be collected.
