The Creator Advanced Models space sets focus on the space theme with two versions of the NASA Space Shuttle know as Shuttle Adventure and followed by Shuttle Expedition. While the 2 shuttle sets looked very simular the builds were very different.
2011 LEGO Sets
In 2011, LEGO collectors saw major milestones, particularly with the release of the first-ever internal LEGO sets, Moulding Machines (4000001) and LOM 2011 Moulding (4000002). These exclusive sets, produced in limited quantities, set the foundation for highly valuable future collector items, making them some of the most sought-after LEGO releases among hardcore collectors.
