Yeah, you don't want your whisk up in the air. That'll cause a mess!
It's either fake, or "Oh shit Nintendo wants a logo from us for the booth so we best knock one up in the next 30 seconds"
It would be a bit odd to have made a full poster and not a logo though; the form in the OP is ordering posters for the booth(s?) As far as I can tell, from the information on the right.
