Signed C. S. Lewis Book, Fake?

I realize this isn't Tolkien, but it is so bad I had to post it. At first, the listing looks somewhat legit, but look at the two pictures of the signature.

Notice anything...

Just goes to show that even with a supposed provenance, a signature could still be fake.

I'm beginning to have less and less faith in eBay.
