Spot the Dog

In 1978, British artist Eric Hill designed an interactive book about a yellow puppy for his two-year-old son, Chris.

Eric had noticed Chris kept lifting up the paper he was working on to see what was underneath and it inspired him to come up with a new format for a children’s book - lift-the-flap.

Since Where’s Spot? was published in 1980, more than 65 million copies of Spot books have been sold worldwide, in more than 60 languages.

Rachel Naylor speaks to Eric’s son, Chris Hill.
