A separately issued example. Subsequently published in the official account of Petit-Thouars 'Voyage Autour du Monde sur la Fregate la Venus pendant les annees 1836-1839' (1840-1843).

The voyage, "ostensibly to report on the whale fisheries in the Pacific, was actually primarily political in nature. The presence of the frigate 'Venus' in ports around the world would be of value to French commerce and diplomacy,... Du Petit-Thouars's account of his stay in California in 1837 is one of the most important and complete records of the Mexican period in California... After visits to Sydney and Mauritius, the ship sailed home, arriving after a voyage of thirty months" (Hill).

Abel Aubert du Petit-Thouars (1793-1864) was nephew of the French botanist Louis du Petit-Thouars (1758-1831). He is credited with bringing the Marquesas and Society Islands under French protection. He rose to the rank of vice-Admiral in 1846.
