Set of 2 old bistro coffee glasses in thick cut glass MAZAGRAN 1920-1930

This pretty set of two old coffee glasses is made of thick blown glass. Called mazagran, these glasses are blown and cut with regular ribs. This is a coffee glass used in bistros and cafes in the 19th and early 20th centuries. He received hot coffee, served at the counter. Some people present them as absinthe glasses, but it seems to me that the latter are more flared at the neck. These glasses are in good general condition and measure approximately 15 cm in height X 7 cm in diameter. I point out small bubbles in the glass and traces of use.
