Well, I'm back in Japan and had a few cards waiting for me when I got home:

Stan160's Albert Memorial, which I know I must have seen while in London, but for the life of me can't remember it. Thanks for the reminder.
gordrob's 2816: a shining detail of an old classic.
Fleath's Hard Rubbish: I too, think you should've taken the chair. And I love the toning of the print. Cheers.

I'm still missing five from this round but that's not bad considering some of the previous rounds. Hopefully I'll be back in round 23!
