This painting illustrates a moment during Duke's visit to Australia. On Thursday, December 24th in 1914, he pulled 15-year-old Isabell Letham (featured on the far left and on the wave with Duke) out of the crowd to tandem surf in front of crowds who had never seen someone standing up on a surfboard, let alone two people riding the same board. This was the most significant day in the history of Australian surfing.
