A NORTHWICH-based company is promoting the Lion Salt Works Museum with a bespoke postmark on its internationally-collected First Day Envelope.

Royal Mail’s colourful commemorative stamps continue to be widely collected and on August 12 an ‘Industrial Revolution’ series will be launched.

Cotswold & Stuart, based in Winnington Avenue, has chosen the nearby Lion Salt Works Museum as inspiration for the design of its First Day envelope postmark.

Emma Moores from Cotswold & Stuart, said: "The company produces internationally-recognised First Day Envelopes for each series of stamps issued by Royal Mail.

"The stamps are placed on an embossed envelope and then a bespoke ‘First Day’ postmark is designed to complement the theme of the stamp series.

"We were thrilled that in August the theme will be ‘Industrial Revolutions’ as it gives us the chance to design a Lion Salt Works postmark.

"The company, which has been trading since 1966, is very proud to be based in Northwich with its rich industrial heritage – after all, not many companies have a Scheduled Ancient Monuments on its doorstep – with the same protection status as Stonehenge and Hadrian’s Wall.

"We are delighted that the Lion Salt Works’ postmark will be sent to our loyal collectors around the world."

Councillor Louise Gittins, leader of Cheshire West and Chester Council said: "This is certainly a wonderful and unusual way to promote Cheshire West’s award-winning Lion Salt Works Museum and we are grateful to Cotswold & Stuart for approaching us with this idea.

"A Lion Salt Museum’s postmarked envelope will be on display in the foyer of the Museum and I am sure it will be of interest to everyone interested in industrial heritage."

The Industrial Revolutions stamp series pay tribute to the Spinning Jenny, Transatlantic Cable, and James Watts’ Rotative Steam Engine as well as the light bulb and the Bessemer process.
