///M most powerful letter advertisment

[RacecarBMW]

So a few months ago there was a small poster at my BMW dealership that had a collage of BMW pictures and at the bottom it said ///M the most powerful letter in the world and something like 1,993 hp (all the m's add up to that)

Im trying to find that ad on the internet but I can't find it. any help please.

I asked the dealer but they removed and have no clue what I am talking about
