Adolf Beckert Steinschönau, Powder Box?

This is one of my favorites glass boxes, it dates to the early 1900 before the first great war. I bought it without knowing what it was for U$ 12 three year ago. It is enameled in black, a technique known as schwartzlot. It was realized in Kamenicky Senov/Steinschönau, most probably for Friedrich Pietsch. People that is not involved in glass collecting adore it because it is very modern and funny. It is about 15 cm diameter.
