The Ironbridge stamp is one of a set of 26 1st Class UK A-Z stamps which feature some of the most famous landmarks from all four countries across the United Kingdom.

The first part of the alphabetical journey commences on Thursday with the launch of UK A – Z Part One which reads from A to L.

Also featuring on the UK A-Z issue is the Number 10 Downing Street front door for the first time.

Prime Minister, David Cameron, marked the launch of the stamp outside the famous black front door of 10 Downing Street today.

The Prime Minister said: “The UK has some of the most beautiful landscapes and fascinating heritage, things that we can all be incredibly proud of. I am delighted to see some of our most loved landmarks on these stamps, celebrating much that is great about our country. Seeing the front door of Number 10 featured on a stamp is of course particularly special.”

Moya Greene, Royal Mail Chief Executive, said: “The UK A-Z Special Stamps celebrate some of the country’s best loved landmarks. It is fitting that the world famous front door of 10 Downing Street is represented, for the first time, in this Special Stamp issue. We are thankful to the Prime Minister for taking part in the celebration of this famous address.”
