J. P. Chenet "Josephine" bottle
Bottles modern
Description
The first J. P. Chenet bottle went on sale in 1984. Les Grands Chais de France conceived of a branded bottle consisting of characteristic curved bottleneck and a large body. The design of the bottle was named "Josephine", with the brand later being named J. P. Chenet after production.
This particular one can't have been in the river for too long, as there is still visible glue on the side.
