This project was a great collaboration with Studio Sutherland. A set of stamps for Royal Mail, each being based on a pivotal point of a different Agatha Christie novel. In the spirit of crime fiction and detective work, as well as using conceptual twists in the imagery, the six stamps contain hidden secrets in the form of microtext, UV ink and thermochromic ink.
Creative Review article on this too, in which they show some of the hidden clues with the special inks and microtext.
Slate also have a great article showing some of the hidden clues.
I'm thrilled to say that the stamps have also gone on to win a yellow pencil at the 2017 D&AD awards, a best in book prize for the 2017 Creative Review Annual and a merit in the 2017 3x3 annual.
