This set of French definitive stamps features the stylized head of a Gaulish warrior, inspired by an ancient Celtic coin from the Parisii tribe. Issued between the late 1960s and early 1970s, these stamps were part of the "Type Semeuse / Marianne et l'Europe" era definitives but stood out for their historical coin motif. The denominations shown here are 0.50F turquoise, 0.60F violet, 0.90F red-orange, and 1.60F lilac-blue. Widely used for everyday mail, these issues are a staple in French postal history and remain popular with collectors for their bold colors and crisp engravings. Postmarks often enhance their philatelic value by showing period usage.
