There might be enough there to suggest that the weird signature is a product of not having a flat surface to write on. That being said, it's a rough example if authentic regardless and I'd pass if it's something you're looking to purchase.

As Rich (who is great on U2 graphs) said, it may well be genuine. But since it’s not a good example of his graph and there is many nice ones out there for not a lot of money I would wait for a better one.
Here’s mine signed in 2015. I got it from one of the best dealers there is and if interested I think he has others!
