Petshop love eating hamburgers !!!
But once a month only !
There are several waves
of LPS's Mc Donald's :
2006 / 2007 / 2009 / 2010 / 2011 /
2012 / 2013 / 2014 / 2015. 
They aren't avalaible in all the countries.
For many people, they aren't considering like "real" LPS because they are in hard plastic and have no number
(except the 2006 and 2008 waves).
Bon appétit !
