Fortnite inspired greeting card?

I have a start up greeting card company and want to print a father’s day card in our local (New Zealand Māori) indigenous language that is inspired by the blue Victory Royale banner with a father’s day greeting substituted for the ‘Victory Royale’ text. The background is a plain landscape image I have bought. It basically looks like a still image of the game.

Would I be able to sell greeting cards of this type?

Please use the Fortnite support center http://fortnitehelp.epicgames.com/ or Fortnite de Epic Games

With that said, we aren’t really able to speak to whether a work inspired by Fortnite infringes our intellectual property, particularly where we can’t see the work. I can say, however, (1) it sounds like you have rights to the background image and (2) Epic doesn’t own blue banners.
