Believe it or not, ‘old vintage sex monks and nuns’ is an actual category on certain porn sites. So we are told. It seems almost endearing to hold on to these antique pornographic and erotic postcards in the age of in-your-face, HD, live action. Erotic postcards like these were the pornography of the 1900s. Pocket sized cards with an ‘oo-la-la’ photograph on one side and a postcard design on the other. They were mainly produced in Paris and therefore known to the world as ‘French postcards.’ Once illegally sold under the counter, now free of charge for monkey spanking monk lovers.
