So here's what a real signature looks like on that same picture. This one doesn't have a cert, but it is very easy to see this one is authentic.

Notice how it is right on the sweet spot of the photo. Notice the formation of the M's and the flow, size and where it is on the photo. Notice the way there is a little flick where the M goes into the a naturally. The c is rounded and not pointing up. Also notice how the half moons end with a little dab of ink. There are other things too that I just can't muster going into. Do it for yourself and you can be an expert in 2 weeks.

There are some authentic ones to that "don't flick" from the "M" to "a", but this is one area I always focus on. It's much easier for me to see the authentic vs. forgery, Not 100%, but 97% isn't bad?
