Today's Write The Book Prompt was suggested by my guest, Eowyn Ivey. Find a photograph or a post card (used book shops or second-hand shops will sometimes have old post cards). Or take a photo from your family albums, maybe a picture of one of your ancestors. Use that as a starting point to writing. Try to imagine who the people are in the picture, and what they're doing. Eowyn has used Alaska's Digital Archives as a resource. The University of Vermont also has an archive of digital images called the Landscape Change Program.
Good luck with this prompt, and please listen next week for another!
