Here's a little something I heard at Goodreads this week:
The striking cover of The FitzOsbornes at War by Michelle Cooper uses a 1932 photograph of Loretta Young taken by Edward Steichen.
This is an incredible cover, IMHO, reflecting the era of the book (WWII, which is close to the '30s) and the character of the protagonist. Sophie is not the smartest, the bravest, the most charming of the FitzOsbornes. She is merely the one who wrote down everything that happened to the other members of the family.
Michelle Cooper refers to the photo and cover at her blog.
I'm guessing that this cover was created by the art department of Cooper's American publisher, Knopf. If I'm right, then I think it's a powerful example of what a traditional publisher can do for an author. Finding that particular photograph and getting the rights to use it is amazing.
