* China exclusive. Contains 3x 40460, 1x 40524, 1x 40647, 1x 40646

* Based on purchased used sets; sealed version of this set is yet to be found and inventoried.

* Contains 851330 851332 854013 with a different sticker, see picture

* I have a of question: I have 2 colors of the same set (e.g. 2141 in both MxOliveGreen and MxBuff). How would I go about adding that to the catalogue? With the current numbering system for the Modulex sets (i.e. Modu0001-1), it seems kind of hard to maintain a good organization, when more is added (I am in the process of adding 7-8 new Modulex sets). My suggestion would be to rename Modu0001-1 to Modu2141-1 (https://www.bricklink.com/v2/catalog/catalogitem.page?S=modu0001-1#T=S&O={%22ss%22:%22DK%22,%22rpp%22:%2250%22,%22iconly%22:0}) and give sets a color variable to distinguish between same set numbers with different colored bricks in them... I have tried to find the answers in the documentation without luck, but please excuse me if it is a "stupid" question :-)

* This 1995 ad was designed to promote LEGO’s 9-Volt trains by sponsoring a special contest in which kids could win a prize. LEGO gave special attention to this ad, going so far as to paste a special brochure which featured comic-book style illustrations. The artists blended together hand-drawn artwork with photographs of actual LEGO sets.

* g81estown and g81detown are similar to this but I think they are wrongly placed in "Catalog" category as they too seem to be board games. (Like 93290dk for instance)
