I need some help identifying the crystal waterglass in this picture. The glasses are from the film "Titanic" from 1997, and the white wine glass and sherry glass are identified as Tudor Crystal glasses, designed by the company for the film. However Tudor Crystal says the largest glass is not from their range. It looks like it is ribbed, but I cannot find any more information about it. It looks a lot like Park Lane from Mikasa, but it is not. The foot is longer and the bowl of the glass is a bit higher. Please help!
