As suggested by Pius Notter and because we were so close (40 min),as the last destination we went to Mulhouse, France. There you could see the ''top'' 30 bonsai in Europe. I put it in quote because I think it is just impossible to select the top trees, because everyone does not like the same bonsai. Ofcorse I must admit the bonsai exhibited there were outstanding.
To the surprise of all of us, there we didn't come to a quality and super organized bonsai exhibition, but to ''just'' an enormous gardening fair.
The trees were shown in a special way. There were no stands, accents or scrolls. they were illuminated from various sides and alternatly. That was great for visitors, but a nightmare for photographers.
Just an example in how manny ways the trees were illuminated. (in between they were also in complete darknes)
