That's the inspiration. Although as you can see, the paper isn't just a copy of an Underground map. Instead, it uses that style for a paper / map packed with city names and with a distinctive orange, black and cream colourway for something that's both a talking point and an interesting detail for a wall too. We say a wall because using this for an entire room is probably overkill, even for a rail obsessive.
A roll of this is around 10m long and 0.52m wide, selling for £75. You can order a sample too.
