Spotted on a late-night District line tube.
A tube advert for something that advertises itself as “#1 investment platform in the UK” with no details as to what it is or how to find it, only an illustration of a rising graph.

From this morning's wander to the Wandle delta, a robin singing from inside the small copse on the Spit. An animated little borb.
