I finally got to see this earlier this week.
The exhibition is a mix of Grayson's own work married with items he has chosen from the British Museum's vast collection.
What can I say? Wonderful, interesting, inspiring, thought-provoking, beautiful etc etc...
No photos allowed inside the exhibition, but the bike he travelled through German is outside, complete with an Alan Measles stunt double. If you can't get get a ticket before it finishes on February 19th then the bike is well worth the climb up the stairs. It's a great example of craftsmanship in itself; covered in wonderful details, and words including Patience, Doubt and Chastity.
Love the man.
Here's some of his older work.
