Then I think Met was transverse stripes, the way they're showing the
H&C (in those days that was part of the Met, of course). I think
Bakerloo was alternate black and white the way they're showing it while
the Central was a string of triangles. That leaves the Piccadilly, and
I have no memory of what that looked like.

Like the Met, but bolder.
