Cool Art: Harry Potter posters by Olly Moss

I was just a big fan of 1950s design and it just seemed like a natural fit. I really liked the idea of Harry getting on a train and going somewhere exciting every year. There is something very British about that. That period of design – and obviously Harry Potter – is steeped in that imagery and I wanted to bring those two things together.

I tried to fill them with as many little details as I could within the constraints of keeping the composition and the viewpoint the same every time.
