Karl Lagerfeld has been everywhere: on t-shirts, coffee mugs, Diet Coke bottles – and he’s currently got a mega retrospective open at the Bundeskunsthalle in Bonn, Germany. Now however, Chanel and Fendi’s creative director is in a children’s book. Where’s Karl? The book, as the name suggests, is a parody on Where’s Wally? (or Where’s Waldo? if you’re American). According to US Vogue, it follows follows a fictional blogger called Florence de la Sabine as she chases the kaiser, along with the rest of the fashion industry, through 15 cities in a year —from Chanel’s haute couture show Paris to the Met Gala in New York and Art Basel Miami Beach.

The idea for the book came from a game that co-author Stacey Caldwell used to play on her frequent trips to Paris: spot Karl. However it was his fans, rather than the designer himself, that she was more interested in: “They would act like they were the only ones lucky enough to spot him, and then two minutes later someone else would do the exact same thing,” she says. Lots of famous faces make an appearance in the book, including Celine’s Phoebe Philo, Givenchy’s Riccardo Tisci and supermodel Naomi Campbell. “That’s the real fun—you think you’re looking for Karl,” says Caldwell, “but you’re recognising all these fashion people along the way.” 

Where’s Karl? is released on September 15.
