Cup on foot openwork chiseled glass

Charming standing cup, in beautifully chiseled and openwork glass. It probably dates from the 60s. Perfect to present some appetizers or even as an original pocket tray. It is in good general condition, no lack, but does not hide its age: it has some marks under the foot including a scratch or crack, I do not know too much, maybe even original, not annoying for the solidity because only on the underside. The glass is a little cloudy in places, maybe limestone (a vinegar bath would probably do him good) and some discreet scratches. It measures 10.5 cm in height, 16 cm in diameter and weighs about 450 g.
