The BIONICLE magazines, which were published in several countries, often came with small gifts or promotional items attached to entice readers and collectors. These gifts were typically exclusive to the magazines or were early releases of items that would be available in sets later on. Some of these promotional items became highly sought-after by collectors, especially if they were exclusive to the magazine and not available elsewhere.
2016 LEGO Sets
2016 saw some truly iconic releases with sets from Ghostbusters and the introduction of the Nexo Knights. LEGO also released the licensed, but short-lived The Angry Birds Movie theme. However, LEGO did discontinue Legends of Chima, Pirates and also the LEGO Simpsons which only did see a couple of sets. The Creator theme really shined in 2016 with the release of the Volkswagen Beetle (10252-1) and Big Ben (10253-1). The shining star that year for investors was certainly the Ghostbusters Firehouse Headquarters and pretty much all the Speed Champions sets which have seen growth in the triple digits.
