A digitally altered image of illustrator Clement Hurd appeared in a newly revised edition of the book “Goodnight Moon”, a classic children’s book written by Margaret Wise Brown and illustrated by Hurd. The publisher, HarperCollins, altered the original photograph to remove a cigarette from Hurd’s hand. HarperCollins said it made the change to avoid the appearance of encouraging smoking and did so with the permission of the illustrator’s estate. But Mr. Hurd’s son said he felt pressured to allow it. Prior to this latest edition, the photograph of Mr. Hurd grasping a cigarette has been on the book for at least two decades.
