Karlovic or Isner, whose autograph did I get?

Question

I went to the Masters In Cincinnati, and I got a bunch of autographs (Djokovic, Nadal, Uncle Tony, Tursunov, Murray, etc) but I am unsure about one of them. I approached a player that was tall (I saw him from the back), but I couldn't see their face. I assumed it was Isner, but now looking at pictures of both, it looks like Karlovic. He had a slight beard. His signature is the top left. /var/folders/H4/H48CRnq FvqacMSyvoqt3E TI/-Tmp-/com.apple.PhotoBooth-T0xc10090.... 845.jpg

Answer 1

mite be karlovic cuz of the beard...but this is a hard one if u didnt see the face and there both the same height pretty much try doing a google search for their autograph and compare yours  

Answer 2

hmm, is Isner playing the tournament? I didn't think he was

Answer 3

Actually Isner did play in Cincinatti, he lost in the second round to Igor Andreev. The question is, did you get it after a match? If you did, you should know who's signature it is. If you remember the tall guy's opponent, it would help.

Edit: It was most likely Karlovic because I don't think Isner has facial hair, let alone a beard.

Answer 4

The link doesn't work. How can you not know who's autograph you got? Look it up on google or something.
