I am no expert at all but (almost) instantly recognised this as an Isle skateboard - the new company set up by Nick Jensen and others. Nick was the driving force behind our project, Whatever It Takes, in Cornwall last year. There are some amazing Isle designs. Had to snatch these photographs on the bus and eventually at the tube station: thought it might have been slightly odd to say 'Can I take a picture of your skateboard?'
Great to see that Isle - only set up in the last 12 months - is already so visibly on the streets.
