Antique Mazagran Bistro coffee glasses from 1900 in thick, cut blown glass

This lovely set of two antique coffee glasses is made of thick, cut, blown glass. Called mazagran, this is a coffee glass used in bistros and cafes in the 19th and early 20th centuries. It received hot coffee, served at the counter. Some 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 7.5 cm in diameter. I note small bubbles in the glass and traces of use.
