Larry Gordon was one of the two most sophisticated marketing minds in surfing history. (The other being Tom Morey.) Larry had respect for the demographic he was speaking to, and that attitude was reflected in the ads he generated. Projecting a "hipster image" was a distant second to conveying what G&S boards were like, and why.
This collection of ads from the late 60's is nearly 50 years old, and they still resonate.
(I love the way the size charts top out at 185 lbs !!!)
