It is not a poor attempt at an a fake katy . This is how she signed some items at kimmel that day . This seller is 100% legit and his other items are legit as well. You cant help how people sign. Celbrities don't sit there and give pristine autographs anymore . Katy signed for over 20 mins . Some were good some were bad.
As for the proof. You should trying getting a photo signed and getting exact proof. If you are selling it , the autograph is whats gonna get you paid , not the proof shot .
Thanks for clearing that up Anthony I must admit that it does look very atypical. but do agree that as others have said he should do more research before "calling out " legit people
Unfortunately, it may take a few months to update through google's search engine results, where it may disappear at a later time. It won't happen anytime soon. I think someone would need to file directly through google for the search result to be removed, which is at their discretion.
