This is a beautiful blue and red French bond certificate from Societe Du Domain De Kebao, a French company likely involved in coal mining operations in Tonkin (northern Vietnam) during the late 19th century.
The certificate is in fine condition, no holes present. Light folds with the bond coupons intact.
Natural resource exploitation for export was the primary focus of French investments in Indochina, with coal being one of the main products. The 1920s saw the continuation of the French colonial system established in the late 19th century, with Vietnam divided into Cochinchina, Annam, and Tonkin at the time.
