Yes, it's now possible for authors to send autographs to their faithful readers. (And I have at least 10 or 12 of them it seems!)
How does this happen when the books are electronic?
Basically, they send you a PDF file with a picture of the book cover and the author's pseudo signature. The great thing is that the author can personalize the autograph. And -- they're FREE! You attach the file to the book in your Kindle, Nook, whatever -- and it's there whenever you want to look at it.
Pretty snazzy, eh?
Where do you go to sign-up? http://www.Kindlegraphc.com
You can request autographs from the more than 1200 authors who've registered. (I'm just one of them.)
What could be easier?
