Yes that's the work of the wonderful Leonard Misonne. A Belgian by all accounts. Not sure if he rode a bicycle too but he should have. Used the Bromoil and Mediobrome processes which are, as I've found out, very difficult to accomplish. I end up with a pile of smudged paper with no sight of the image that I wanted. Especially no sight of such lovely images with with wonderful use of backlight. And seeing this must have been taken using old un-coated lens' on plate cameras, that is quite something.
I have a book with his images bought in the Photographic Museum in Charleroi - where Mr Misonne was born - that I would not part with. Have a look round the tinternet, there's some lovely work of his on show there.
