I know from a good friend in Bristol that the “smaller” variant (just a regular one-parter) was common in Great Britain. That one has double the width (8’1”), the ponies from the movie and appeared in just one store as far as I know.
 
What a luckfuck I had when I visited that store in Berlin by accident by the end of last year! They told me on the phone in November 2018 that there were no my little pony decorations. Well… if the store manager looks in the My Little Pony section but that banner was placed somewhere else no wonder they couldn’t find one…
 
So I reserved it and what a luckfuck again, they called back to pick it up!
