This was shaped by legendary surfer Mike Hynson in the Rainbow days BEFORE they used the "shaped by" print and glassed it in. I have added a few extra pictures to show he sometimes signs "Hy-" as his name. Since this has a psychedelic flower and "Hy-100", maybe this is his 100th board ever shaped??
I can't confirm it is his 100th board but it definitely is a piece of surfing history shaped by a master of both surfing and surfboard making. Own a piece of history!
