Well I can't say I've ever heard of them. I tried looking them up online but all I can find is this playboy deck and a green-ish deck. Do they have a main website? And what other decks have they made?
You probably haven't heard of them because they're a clothing company based in Japan, now owned by a Hong Kong fashion conglomerate called I.T.

As the article will tell you, the brand has done many works with other companies and their cultural icons - this Playboy deck would fall into that category.
