Before you get too impressed let me tell you a bit about the process. You get extremely pixelated production photos of the actors wearing the products with about 123,355 watermarks on them and no close-ups.

When I find myself at Kings Cross, I still occasionally see somebody rocking them on their way to Platform 9 ¾!
