The art inside a snuff bottle!
A snuff bottle is a very small bottle that contains powdered tobacco and other ancient Chinese ingredients. It is believed that depending on the contents of the bottle, sniffing the tobacco can alleviate many common illnesses such as headaches or colds. Snuff bottles were mainly used during the Qing dynasty — an era when inner painting was invented. In this art form, which is still practiced today in China, the artists use specially designed pens to draw on the insides of bottles.
