Advertisement for Absinthe Duval showing the tallest pine tree in France, situated in the Joux forest just outside Pontarlier. The connection to absinthe is not immediately clear (!), although Pontarlier is known for its sapin, a liqueur made from pine buds. This picture originates directly from descendents of the Duval family, and is possibly a one-off photographic mock-up made for proofing purposes, rather than a commercially distributed item.
