6 Antique Perfume Bottle Samples Holman & Narcks? Negro

Collection of 6 antique glass perfume bottle miniature samples. 4 have Holman on the label. The 5th can be worn as a charm with brass screw top that has a pendant ring. It is hard to make out but looks something like Narckso Negro. Each has remnants of dried perfume and a little scent. Included is one more bottle that I found that has light green flashing that has crackled and its cork has glass dipper. The corks are old and crumbly. All show wear but no damage. The bottles range from 1 7/8ths tall to 1 1/2 tall.
