On further inspection of the U.K. Price sticker it is also interesting to note the toy shop is The Entertainer, Amersham which according to wiki was the first shop of the still successful and ongoing brand that started out in 1981. I guess, if someone was so inclined, they could write to the owners of the shop who still run the business, Gary and Catherine Grant to find out. From what Joe said it sounds perfectly plausible that they filled the shelf for a while and were sent back, which is pretty much the business model for today's toy shops.
