As we're sure you're all aware, Nintendo has dabbled in many different business spheres, including toys, hotels, and even taxis, but it began life as a card manufacturer, making "hanafuda" cards.
While the museum references this part of the firm's past, it doesn't include a product which, to modern eyes, might seem unbefitting to Nintendo's family-friendly image: nude playing cards.
"I imagine most Nintendo fans won't know that they made nude or erotic "pin-up" playing cards, particularly in the 60s and 70s," says Mario Museum. "I wonder if the Nintendo Museum has a special section behind a curtain. This is also the first time I've put a nudity warning on a Nintendo tweet!"
Produced during the '60s and '70s, Nintendo released multiple decks featuring naked ladies – a fairly common novelty in the world of playing cards during these decades, it should be noted.
According to Before Mario, Nintendo often produced these decks for other companies; for example, Japanese whiskey giant Suntory commissioned a pack.
As Nintendo shifted towards making toys like the Love Tester and Ultra Hand, it stopped producing these saucy decks.
