On August 2nd 2013, exactly five years ago today, there was a clutch of orange umbrellas above Lower Marsh. (Also (see bottom right), 240 Blackfriars Road was under construction.) I don’t believe I mentioned these umbrellas at the time I photoed them, and now, I can’t google my way to any sort of explanation of them. But, I think I recall investigating them at the time, and I think they were some kind of advert for an art gallery. This guy agrees that these umbrellas were indeed there, then, but he doesn’t say anything about them either.
Anyway, here they are, as I photoed them then:
The bottom left one looks to me like the head of some kind of oriental feline creature.
