Absolutely no clue how old it is. The bottle is pressed glass with no chips cracks or flea bites. Clean inside. Perfume? Smelling salts? It measures 1 5/8" long including the cap but not including the loop or bail above the cap by 1 1/4" wide by 1/2" thick. Perfume bottle is in MINT condition - UNUSED and has a SILVER TONE cap. The chain is a 28" heavy silver plated box chain. Only one I have.
