Authentic Autographs on Amazon?

There's a shop called Authentic Autographs on Amazon. The autographs look good to me, but sometimes the exact same autographed photo is listed twice? This makes me a bit skeptical, but it could be a mistake. Has anyone ever had experiences with them. What do you think of the authenticity of the items?

Here are some of the Jennifer Lawrence's:

I'm pretty familiar with her signature, but sometimes it's hard to tell with her rushed signature.

I wouldn't buy it if you aren't sure. They don't look convincing to me either.
