Patriotic posters dating back to the 1930s which urge shoppers to 'buy British' have emerged for sale.

The poster campaign was created to get Brits to stop importing foreign goods in a bid to boost the economy after it took a major hit in the Great Depression.

It was fronted by the then Prince of Wales who said in 1931 that the nation was buying 'more than it could afford' from abroad and that Brits should 'buy at home'.

Posters were issued on a weekly basis to factories carrying slogans demanding workers to do their bit and purchase local goods.

The copies of all 26 posters that are now for sale in Dorset were kept by a factory owner who took them home. They have subsequently been passed down the generations to his grandson.

After rediscovering them in his attic while recently moving house, the vendor has now consigned the posters for sale with Onslow Auctions, of Stourpaine.

They are tipped to sell for £5,000.

One poster has a picture of a horse with the caption 'plain horse sense - buy British and protect your jobs'.

Another has echoes of Lord Kitchener's famous First World War recruitment poster with a person pointing a finger at the reader.

There is one depicting a young brother and sister at a shop counter asking the cashier 'I want the kind my Daddy makes'.

And another poster shows a rugby match pleads 'buy British and pass your wages to another member of the British team'.

Patrick Bogue, owner of Onslows Auctions, said: "The posters were issued to urge British people to buy goods made in the country instead of from abroad at a time of economic depression.

"They are numbered one to 26 and were issued every week to be displayed at factories.

"The message is very similar to what is going on in this country at the moment with Brexit.

"They belonged to a factory owner in the 1930s and were inherited by his grandson, who had them stored away but rediscovered them when moving house.

"I believe these posters were only issued in factories and they were likely destroyed after use so to find surviving copies is in fact quite rare."

The sale takes place on Friday, December 14.
