Cool Maya GT shot - but who is that man?

Another great shot of the Maya GT 'HPN 13D' was found recently in a 1967 Dutch motoring magazine. I am not sure but suspect the man standing proudly next to it is the boss himself: George Holmes - anyone who can confirm this? The car was used for one of the brochures and was raced by a Mike Greenwood, but I still haven'tt been able to find out anything more on that. See here for more information about the car and click on the registration numbers below for all the other Camber GTs and Maya GTs that I have researched.
