Someone please correct me if I'm wrong, however as I understand it, yellowing of bubbles is caused by bromination of the plastic. In other words, an unwanted chemical reaction caused by impurities in the plastic at source. I don't know that temperature has much effect either way (although obviously temperature can have a profound effect on some chemical reactions, I wouldn't have thought that the average temperature difference between Scandinavia and the rest of the world, combined with the length of time that has passed since the original date of manufacture, would be enough to make any significant difference to the bromination process). From the day a MOC left the factory, it's bubble was always destined to either go yellow or stay clear depending on whether there were any impurities in the plastic.As everyone has mentioned it looks fine.
A question if I may…with the climate being cool in Scandinavia are all the Jedi carded bubbles yellow?
I would have expected them to be clearer than ones from Europe?
thanks mateLooks good to me. Great stickers!
thanks mateNice. All looks fine, not a reseal.
thanks for the helpThat's all good. Nice one!

thanks for all the great infoLooks like a very nice example to me. As for the yellowing, perhaps sunlight light and temperature play a part. But if that's true, then I'll also add that "being kept in the dark" turns bubbles yellow too! The majority of my MOC have been stored in a dark closet for 20 years and most of the bubbles went yellow when I looked at them again recently.
The unfortunate truth is that bubbles will either go yellow or not and I'm not convinced there is much you can do about it. If it is still a sealed example, then just enjoy that as the main thing. These things are as old as us. They age just like we do.
