navigation issue

The Navigation and Commerce issue is a series of key type stamps issued for the colonial territories of France. It was designed by Louis-Eugène Mouchon.
The issue uses a standard design featuring allegorical representations of navigation and commerce. The territory name is imprinted in a rectangular cartouche centered at the bottom of the stamp.
In French colonies, it is the first series of territory-specific postal releases. Adding the territory name helped reduce revenue loss incurred when stamps were purchased in colonies with low-value currencies, then sold or used in colonies with high-valued currencies.
It was first released in 1892, with later releases featuring new color schemes. Dates vary by territory, but by 1900 values start appearing surcharged in red or black ink to use the remaining stocks while colonies then used illustrated stamps.
