Florian, What part of PQ are you in? I lived up there for a couple of years back in the late nineties. I would attempt to rap with you guys in Quebcois but my abilities in the French language are long gone.
I am pretty sure this is just a souvenir from someones trip to Japan. It is pretty cool and will be good for Halloween or something. If I could learn to do hand rolled edges I could chop it up and make some squares for the masses.
