Maybe it is a Lemon Turd Cart
Not constructive and your comments are making me look stupid. But thanks anyway.
I disagree Jane. That comment is in
no way making
you look stupid.

When I first saw the photo I had in mind a Suffolk location too Jane, however I think that perhaps the cart and the water gave that impression.
Zooming in I am not so sure. The bridge with the taller buildings behind made me think of somewhere 'continental'. I am unsure why, perhaps it is seldom that in the UK you will see a rural scene with bridge and tall buildings, and perhaps I would expect to see 'lower' buildings.
(Upon thinking again, I am not sure that statement is correct ....

)
It is a tricky one because that scene is unlikely to exist today. Some people have had luck searching for the same postcard (but named). I think this has happened on a couple of "mystery location" threads.
