“La Parisienne” opera glasses

Pair of flash binoculars from the French brand "la parisienne". Sold by street vendors in the first part of the 20th century and offered today in its original case, this unusual object will make its effect with its multiple functions: opera binoculars, simple magnifying glass for reading or double magnifying glass for examining, telescope, simple or magnifying mirror, or compass. However, as the charm of the old rarely goes without its share of small drawbacks, this little gem has a problem indicating the north, specific to all similar models. Hasn't it become its trademark? Open binoculars: Height: 4cm. Width: 10cm. Depth: 10cm. (1930). A souvenir from another era, this object may present some tests of time.
