What it is
A 1921 Underground poster for the Museum of Practical Geology in Jermyn Street. A jagged black and grey stibnite crystal rises over a low, broken skyline.
Why it matters
Kauffer made the mineral the whole argument. The lettering names the stibnites, the stations at Piccadilly Circus and Jermyn Street, and the words Travel By.
What to notice
The museum name is set in pink, with a lowercase i slipped into PRACTiCAL. The Underground stamp sits low on the right.
A crystal as tall as a building, to get a city into a museum of rocks.
