This is a postmark or cancellation from Champagnole, France (southeastern France, near the border with Switzerland). The tourism site for the region gives this information about the church:
St Cyr and St Julitte church Built in 1755, the tabernacle was built in 1764 and demolished in 1793. It was replaced by an altarpiece from the Ursulines located in Poligny in the 17th century, and bought in 1792 after the cancellation of the convent. In 1788, the church was judged to small, and was extended with two aisles. The organ was built in 1721 by Marin Carouge (postman), he took a seat in the Dominicans church of Poligny, and it is only after the French revolution, in 1792, that he became ownership of the Champagnole church. In 1807, he fitted out in the rostrum, especially erected. He remains a jewel of the cultural heritage of Champagnole.
This site discusses the organ which was installed first in a convent in 1721 and then moved to its present location in 1792. The organ was restored 1988-1989, which is noted on the cancellation. This same site also provides some delightful recordings of the instrument.
The clipping includes the stamp, a fairly common "Liberty" stamp of the type issued in 1982 (Liberty after Delacroix). This 2-franc coil stamp in emerald green is Scott 2080 issued in 1987.
