Recently listed these after getting them back from CGA and pretty shocked by the interest… don’t think either will be in my possession much longer so just sharing while they are!
If you don’t know the story on Inside Tours, they happen annually in Billund, Denmark at LEGO HQ. It’s a whole thing to apply but they select very few people. Nowadays there are several tours per year (like 4-6 I believe). Back in 2012 there was only one; two tours in 2014. Attendees receive custom sets, sealed, serialized, signed by the set designer, with a picture of the group on the back. Obviously most sets are opened / built by the attendees but I managed to grab these a couple years ago (in both cases it was a couple that attended, so they had an “extra” one they were willing to sell) and just had them graded to pass to the next person… doesn’t get much rarer than this for modern age LEGO!
