Museum of Miniature Found Objects

I noticed this vehicle one morning earlier this year, near where I live in London. I'd walked past and then thought, 'Hang on a minute . . .' and had to walk back to check. I saw it several more times over the next few months, parked in the same spot, but sadly never saw the driver or passengers. I like to think of them as thin, slightly vague people, not given to any sudden movement or much conversation, but with a general air of amiability.
