Images of the 2015 LEGO Employee Gift set has surfaced through secondary marketplaces including Bricklink and eBay. Every year, LEGO employees receive a free gift from LEGO. This year, it is LEGO Kladno Campus with set number 4000018. Prices start at around $150 USD. It is interesting to note that almost all of the sellers are from Czech Republic so folks there may have gotten their LEGO employee gift a bit earlier. Thanks to Patrick for writing in.
