Is this a real deck?

This card and a Hanged Man card features in the third season of The Originals (Vampire Diaries spin off). Is is a real deck or one of those 'made for telly' ones?

Whoaw I like this knight of pents a lot ! Mmmm.... If all the cards sport the same quality of design, I hope it turns out to be a real deck !

Now this is interesting. I hope someone can identify it. You don't always find a Knight of Pentacles this badass. Even his horse looks formidable.
