In the lead up to the 2014 World Cup, the craze of World Cup stickers — and how much it could cost you — has attracted a lot of media attention.
There's even a blog by Simon Whitehouse and a mathematics paper by Sylvain Sardy and Yvan Velenik that explains all the maths involved.
It broke my brain slightly, so I decided to make something to actually show you how difficult — and expensive — this part of the World Cup can be.
So how much might it cost you to complete your album — without swapsies?
And be warned, that last obscure card is a real pain to get...
As you've probably noticed, this is taking longer than England's wait for a second World Cup. Maybe make a cup of tea and check back later while we diligently finish your sticker collection for you.
