Same room, different corner.

Photographing through the glass, the writing is unfortunately not really readable. But these are some of the mentioned memorabilia. Each with a sign telling about the origin story and a few details about the object itself.

This might just be one of the most famous adresses in London, even though it was a fictional one for quite a while (the street obviously existing, but not the number): 221b Baker Street and the Sherlock Holmes Museum within. There is a slight catch however. The museum is owner of the adress nowadays. But it's actually situated between 237 and 241 Baker Street.
The museum itself is well worth a visit. With a huge number of contemporary artefacts, memorabilia of the various Holmes stories and many pieces of information that sometimes might even surprise a Holmes expert.

A similar view to the first, but going down now and a bit darker. Including the Jubilee Gardens with a small (and I think only temporary) amusement park next to it.
