One sees this bottle in different sizes and a variety of colors including light blue, green, clear and purple.

This is a 20th century Wheaton, NJ re-imagining of earlier 19th century bitters bottles. Calling it a reproduction is not quite accurate since there is no exact example found in original bitters bottles.
These have a small amount (as in a few dollars) for an individual - perhaps a bit more if they are in sets.
