This isn't run-of-the-mill blotter acid, this is some kind of souped-up Scandinavian hallucinogenic called Bromo-DragonFly, and as you can see, a new product needed a familiar pitchman to get a beachhead in a new market.
Cops in Helsinki, Finland raided a drug den and confiscated that sheet, plus a bunch of cash and other tools of the drug-making trade. Winners don't do drugs, but just in case you guys were thinking about licking ingesting something with Mario on it, this won't double your height or allow you to throw fireballs. Cops say this stuff "leads to addiction in addition to strong delusions, anxiety and physical symptoms."
Since it takes about 25 years for cabinet art to make its way to hallucinogenic stamps, I suppose we can look forward to some Mortal Kombat acid in 2017.
