We made our way over to the recently revamped London Transport Museum this weekend, and wow, what a treasure trove of graphic brilliance it is.

You're given a folded card-guide of the museum as you go in, and as you wander round the museum you punch the card at thirteen stops that mark out different areas of the exhibition. It's a really smart way of encouraging kids to explore the whole place.

You kick off your journey by taking the lift to the second floor. As you ascend, the usual floor indicator LED sign instead shows the years ticking past in reverse, so that you travel from 2007 back to 1800. There's an accompanying set of audio-clips that help to make you really feel that you're heading back in time. It's a charming and simple way of getting your imagination in gear.

The exhibits are the expected examples of tube carriages, hackney cabs, models of stations, and even some waxwork figures; but what really stands out is the wonderful collection of graphic ephemera. The walls are covered in fantastic posters from across the years, and there are several plan-chests full of bits and pieces of ephemeral wonders.

There's a great shop (naturally), with a particularly fine poster collection (which you can browse online too).

The ones above are by (from left to right) Alan Fletcher, David Pocknell, and Man Ray.
