Postcard design - Collected postcards

Below are postcards i have collected over the years as i have always found it interesting, how something so simple and small can be designed to have something with a huge impact on the front and sometimes the back. I particularly like the postcard from the top image, third from the top, second row down. It is an image of two children in a fantasy forest setting with floral designs, which made me think of Hansel & Gretel This gave me the idea to create a set of postcards from a fairy tale. I will look into Dark and edgy fairy tales to fit with the theme from "the Edge" set by 'DontPanicOnline'
