"Antique Engraved Bohemian Tumbler"
This beautiful engraved tumbler bears, on one side, the date 1789, but I am convinced that the object was made at the beginning of the 20th century. On the opposite side, a work scene also engraved by hand: two workers engaged in the manufacture of sheets of paper.
