This is a bitters bottle made by Wheaton Glass Company back in the 60's - 70's. I believe this may be a reproduction of a flower bitters bottle which was made in 1850. Beautifully colored in amethyst and in very good condition, with the typical bubbles and slight imperfections throughout which occur during the manufacturing process. No cracks or chips, but it does have several small scuffs.
Measures 5 1/2" L x 2 3/4" W x 9" H
