Rev Paul Martin, the superintendent methodist minister for the Leigh and Hindley areas, will be giving a talk next week on his extensive collection of naughty cartoons.
The 49-year-old often attracts puzzled questions from his audience about why a religious man is giving talks on such a risque topic but he says it's all a bit of harmless fun and he first started collecting the cards by accident.
Rev Martin said: "I was working down in Cornwall at a kind of 'Christian Bultins' and I started collecting black and white postcards because I was a student at the time and they were cheap.
"Word got around to my friends that I was collecting them and, through Chinese whispers, it eventually became 'Paul is collecting naughty postcards'.
"Barely a week went by where I didn't get sent these cards.
"I was often asked to give talks over the years and, when they wanted something non-religious, I didn't have anything else so I did it on the postcards.
"I've done a lot of reading around their history and looked at how the cards portray stereotypes and the themes running through them."
He has now given talks on the history of the saucy postcard more than 100 times and the people of Glazebury will now be able to hear his fascinating tale.
The work of artist Donald McGill, who was prosecuted on obscenity charges for his postcards, features prominently in the talk.
Rev Martin will be giving the illustrated talk, complete with slide show, at Glazebury Methodists Church, Warrington Road, on Wednesday June 18.
It starts at 7.30pm and admission is £2.50, which includes refreshments.
