Sorry Fred not close enough with Amsterdam... But it is a 40 minute bus ride from Amsterdam
It is not Rotterdam either... wrong direction from Amsterdam

I will answer question two just to blow you away...
The murals are made from cigar bands... In fact 11.5 million of them.
Following WWII cigars became available again this gentleman started gluing the bands together to make these amazing walls in his house.
Later the walls were transferred to this town's museum.
