Issued in 1906 for the French Post Office in Tchongking, this 4 centimes stamp in brown purple is part of the Type Grasset series and features an overprint reading “Tchong K'ing” alongside a Chinese denomination. Designed by Eugène Grasset and printed typographically at the Imperial Printing Office in Paris, the stamp measures 20 by 24 mm and is perforated 14 x 13½. It was produced on bluish paper and embodies themes of goods and mythology, echoing the French Republic’s allegorical style and its commercial presence in China. Catalogued as Scott TCH 19 (Michel FR-IC B37VI, Yvert FR-TCH 50, Gibbons FR-TCH 19), this example is mint never hinged with pristine gum and no faults, making it a well-preserved representative of French foreign post operations in early 20th century Asia.
