The impressed marks on the bottom (D.R.G.) stand for Deutsches Reich Gebrauchsmuster (German Reich Registered Design); the flask was used in the early 20th century as a means to reduce the spread of tuberculosis, then a common and deadly disease; patients kept the flask with them to collect sputum and, when full, burned the contents for safe disposal; this model was sometimes known as a Blue Henry, being made of cobalt blue glass.
