Is moorcroft somewhat of a special brand, so that's why they're so expensive?
I suppose it is. According to Wikipedia, the company was founded in 1897. Also, these appear to be limited edtions and numbered.
There's no way I'm going to buy these, especially since they would have to be
shipped across the ocean, who knows if they would even reach their destination in one piece?
Apart from the picture and colouring books, this is the only merchandise released so far, although there appears to be more to come.
