Bonsoir à tous, je recherche désespérément cette polices d'écritures, ça serait vraiment génial si quelqu'un pourrait m'aider à la trouver

It's a tough one you have given us. I hope someone figures it out for you.

When I saw it the other day, I thought the animation of the letters makes me reminded of Burbank from House Industries. It isn't but that probably could be used in a pinch. http://www.houseind.com/t/7a74b2

I looked through a font identifier - and it comes up with a Dafont one - also not the font - but maybe as a substitute.
BP Mono Bold - http://www.dafont.com/bpmono.font?text=PEANUTS

Good luck - again, I hope someone finds the actual font for you.

Thank's for your help But unfortunately that does not correspond to what I wanted. The police is "Snoopy" apparently, but I do not manage to pierce her free of charge :/
