I stumbled upon these two signs by accident. Like most people here, I like to research what the fake signs look like before buying but at 35 bucks for the both of them, I rolled the dice. They both look good to me, but admittedly, I have no idea what knock off No Nox signs look like. I've never come across this particular Gulf tire cover before either.

The seller insisted these are real and based on his other items and general feel of the guy, I don't have a reason to think he is knowingly pushing bogus signs on people.

What do you think? Are they both real?

Thank you in advance for any information.
