This joke optical illusion card is Copyright 2001 James Dalgety. It came into the collection as part of the Grand Illusions (www.grand-illusions.com) Christmas Pack 2018/2019. James based it, with permission, on a much earlier card that he saw when he visited the Davenport Collection. Should you follow the instructions on the card, you won’t see a nodding donkey, but people watching you will see one.
