All right, this goes above and beyond all corporate promotional genius ever. The annual report from Podravka, a food company based in Koprivnica, Croatia, has its own title: Well Done. And although at first glance the contents appear blank, if the book is wrapped in foil and baked for 25 minutes at 100˚C, the text and images—recipes and a company audit, printed in invisible thermoreactive ink—will appear. However, according to the design magazine Dezeen,
If you are not precise, the booklet will burn, just as any overcooked meal. If you have successfully baked your sample of the annual report, the empty pages will become filled with text, and the illustrations with empty plates filled with food.
The designers, Bruketa & Zinić, add: “To be able to cook like Podravka you need to be a precise cook.” And, I might also add, nobody wants to be thought of as a book-burner… or to have to request a second copy because they didn’t watch the time. That’s one way to make your shareholders pay attention.
