A CACHE of saucy Second World War postcards produced by Bamforth's of Holmfirth, is set to provide a cash windfall for their lucky owner.
The 500 kiss-me-quick style cards were discovered in an attic and are thought to be the unsold stock from a seaside novelty shop in Wales.
Items date from the 1940s when Britain's holidaymakers were trying to forget about petrol shortages, food rationing and the threat of invasion by Adolf Hitler.
They were created by Bamforth and Co, the postcard business founded in 1870 in Holmfirth.
Each of the cards is in mint condition and highly sought after by deltiologists - as postcard collectors are called.
The cards, with their prim matrons, busty landladies and randy squaddies, will be sold on Tuesday, July 27 by North Wales auctioneer David Rogers Jones.
Mr Jones has estimated their value at £200-£300, but they could sell for much more.
His saleroom in Colwyn Bay is just a few miles from where they were discovered.
He said: "The postcards have lain in the attic of a Llandudno property for years but they are in mint, unused condition.
"At the height of this area's popularity as a destination for holidaymakers and day trippers, there were dozens of shops selling souvenirs and racy postcards to send to friends at home.
"Judging by the quantity and their untouched quality, we believe these postcards were stock from one of the shops."
At its peak, Bamforth's produced 16 million cards a year.
"They are a snapshot of an era when smutty double entendres were just vulgar enough to be funny," Mr Jones added.
"The country was at war and the humour in these cards gave folk a much needed a lift," he said.
And his favourite card?
"I particularly like the one showing a young woman in bra, panties and suspenders with her dress and gas mask over her arm.
"The verse reads: `When the air raid sirens shriek out loud, What funny sights there'll be, People dashing out distressed, Some in nighties, some undressed! Oh, damn the black-out it's too dark to see!'."
