Antique Larkin & Co. small clear glass bottle,  possibly used for perfume or other cosmetics.  Larkin & Co. of Buffalo,  New York, is embossed on the base of similar bottles. Date to the late 1800s or early 1900s. The absence of a rough " broken-off" base (a feature of much older, hand blown bottles) and the likelihood of a side seam running over the lip suggests it was produced with an automatic bottle machine,  likely dating it to after the 1910s.
