Yes, IMO. Very nice, is this yours? I have been watching a JSA authenticated drum head which matches these signatures perfectly. It has been authenticated by James Spence, but it's missing Jason...$425 which i would gladly pay if it was complete
I stumbled over the same observations as you Mark. I am still comfortable with it. I have an in person Entreat signed and my O touches, however not as seamless as the above poster. One thing the O has going for it, is that it starts and finishes on the left hand side. Also I have seen the down stroke on the R on the inside many many times. Lastly I have also seen the long flowing tail before, but i agree not typical. Perhaps Robert actually had some time to sign and wasn't rushed :). Plus the other gents match up pretty spot on, in my opinion. Below are some examples of some friends pieces, personal and other trusted pieces.
