Antique Collapsible Cup Approximately 1915

Gorgeous little collapsible cup. Approximately turn of last century. Handle lifts off of its ball via hinge and collapses. I have tested this and it functions well to retain contents without leaks. Gilded interior. Showing a century of use on exterior with wear from being opened and collapsing. Interior has a mark at bottom. I shave washed this but not scrubbed or scraped at the mark. Selling as found.
