Wellington-based artist and author Bob Kerr didn't have to look far for inspiration for his new book.
He found it in a suitcase on top of a wardrobe.
It was full of photos his father had taken on his journeys around the world as a merchant seaman, including during World War Two.
Bob's incorporated those photos and stories in his new graphic novel Jack and Sandy: One War, Two Friends, Three Generations.
The character of Sandy is loosely based on his father Robert, who was third engineer on the Sydney Star when it took part in Operation Substance, which helped supplies to Malta in 1941.
Bob is well-known for his historical landscape paintings but is also an award-winning children's writer. He was the co-creator of Terry Teo and The Gunrunners, which was twice brought to the screen - first in 1985 and again in 2016.
