The banners have the same dimensions as the ones from the US (>>1975358) but the vinyl is softer. And velcro is used for displaying.
There’s this three-parter being the most common decoration in Germany since three shelves were used for MLP. A few stores were equipped with a two-parter (>>1983567) and there was only one store in Berlin with a one-parter with the same width as the two-parter (>>1983563).
The rate of 2 out of 67 stores in Germany speaks for itself: Those decorations are not to be meant for collecting them. I know a good friend near Nuremberg who also despaired in collecting them.
