A group of stamps from France, issued 1997, depicting the journey of a letter in cartoon form; a very envelope centric issue as the envelope is shown on all five. The envelope even writes the letter and collects the kisses in the end!
Mine is the regular old-fashioned gummed strip, perf 13.
Yv# B3065A comprising 3060-3065 / Scott #2580a comprising # 2575-2580
