Okay, so I may be a little behind (May 2nd - I know! super old! but still cool!). Give me a break, I just stumbled across this information this afternoon. :)
Sarah Boynton, author of The Going to Bed Book, is the first author to sign an e-book. 8 year old Alex, in the picture, is the first person in the world to receive a signed e-book! Hosted in New York by Barnes & Noble on Monday, May 2nd, Sarah Boynton read her book, The Going to Bed Book, and had a book signing.
Some, like Alex, had an e-book for Ms. Boynton signed, but the majority still brought a hard board book up for her to sign!
