So my Dad went to Hawaii in 1969, not as a surfer but as a tourist and I grew up looking at a souvenir he got that was on our bookshelf for 40 years. Then I went to Hawaii with my wife in 2016 and we are walking around a a tourist shop on Oahu and I see his souvenir. almost identica so I bought it. Anyone know the significance of this particular item? I googled it but no results. The one on the left is his; bought 1969, the right bought 2016.
