852856 Max Key Chain is a Key Chains set that was released in 2010. The LEGO Group gave Max key chains to those who signed up for a particular LEGO club meeting. Nobody else in the world was entitled to the chain except LEGO club meeting members. This key chain is very special: its minifigure is exclusive to this key chain. Max's hair is also exclusive in this colour, and the shirt and head only appear here. Max is well known for appearing in the LEGO Magazine as represented with cartoon pictures. This key chain is the first containing a comic character that doesn't appear in any particular theme.
