I live vintage Iittala glasses and have a hard time resisting them. This is the Marski pattern designed by Tapio Wirkkala. They're very similar to the Romantica, but shorter, and the stem is thicker. They're sort of the Romantica's burlier brother. They were in production from 1959 to 1980, but some online research shows they may have had a limited reproduction period around 2000 - those had the Iittala mark etched onto the glass (the foot, probably), while these vintage ones are unmarked.
