Alexandra Beatles London is part of the graffiti wall that greets the visitors at Abbey Road Studios in London.

The studio https://en.wikipedia.org/wiki/Abbey_Road_Studios and the famous crossing nearby is internationally known for The Beatles recordings -- and yes, that photograph!

The walls are painted from time to time and as such there's a cycle of graffiti that appears an disappears over time. I find it similar to Twitter feed and its tokenization.
