He said "An completely incongruous bit of underground station in the Bournemouth Oceanarium. I have little idea what it's doing here, other than perhaps to convey that we are "underground" - except why would there be an Underground roundel like this?
Also of note: the Underground roundel and the sign both use Arial and not Johnston. Not that I'm a font geek or anything."
If anyone has any theories on why a bit of the London Underground has been transported to the Oceanarium, please let us know.
Also if you have photographs of any other parts of Tube stations which aren't in London, please send them my way. It makes an interesting addition to the Roundels not on the Tube set.
