You could tell what type of man Captain James Cook was by looking at his signatures, says a historian.
Rare personal letters and draft journals from the explorer show he even worked on it and rehearsed it before it became his impressive scrawl.
"His signature is so obviously a signature of a great man," said Paul Brunton, emeritus curator of the State Library of New South Wales, which owns the historical collection.
The documents also reveal that after his first landing at Gisborne, Cook regretted that a number of Maori lost their lives.
