Actually this is not Greg Russell but another Greg, the guy who is linked in my comment directly below yours.
There is a photo of Greg Russell in the seventh gallery (:: Venice Locals Surf and Skate #5 (#2 by date) ::)
He is the 12th photo. ( https://pbase.com/venicepix/image/46031326 )
I knew Greg Russel quite well but not very many people seem to remember him. If you do, you might consider leaving a private comment here with an email address. I'll get in touch.
