Hi guys I hope this is the right place to ask this question. I've got a London Underground map jigsaw puzzle. I have already assembled it and it looks great. However, it was sold in a bag, without the box, and I have no clue what year it reflects. I assume the information would be on the box, but as I have none, I was thinking some aficionados might help me A pocket map which I have at home dates back to 2010, when I was in London, and I have compared the jigsaw with it. The main difference is the Emirates Air Line. It was opened in 2012, so the jigsaw map must be at least 7 years old (it may as well be pretty up-to-date). But I'm a laywoman, so I can't do more in-depth research. Could you please help me?
