Description
This mug was produced in two plants. Starting registration - sixties. It replaced the circles with twisted faces, arches and other excesses of the Empire era. I do not know who copied the drawing - the builders on the glass blocks in this mug, or vice versa. Produced circles volume of 0.5 and 0.25, and with the number of faces 14 and 16 has the same fate as the bar. Last mugs were released in the 90s.
