Vintage French La Fontaine brass opera glasses with a case are elegant and collectible items, often reflecting the craftsmanship and style of late 19th to early 20th-century France.
 
These small binoculars, known for their ornate design and functionality, were popular accessories at opera houses, theaters, and other performances, allowing patrons to better view the stage from a distance.
 
This is a pair of early 20th-century French (Paris manufacturer) opera glasses in their original case. The glasses are in good condition considering age and use, and the lenses are undamaged and clear.
 
The case is embossed with the maker's name and address and is in good condition for its age, although the strap has become detached at one end (see photographs). The closing mechanism still works.
