All the Rock Designs tees were designed by 'us' at Vertebrate Graphics, the blond guy, main artist back then was Simon Norris, drawer of the chainsaw pic above, Andy Burgess was the main man, and Paul Evans also did tee designs and other stuff with Simon (and me). RD was taken over by a printer years ago, and we stopped working for them about that time. We still have rights to the designs, but actually have very few of the actually designs - it was as you say back in the day!
We are still designing climbing tees...some neat work coming out this spring.
