I would assume the two names are the person who blew the glass and the person who cut/decorated the glass maybe? and that the name of the piece is 'Aqua' meaning water rather than a colour.
It looks to me as though it might be a piece made by Irene Frolic whilst she was over here perhaps? the date doesn't tie in though with Northlands I don't think. Is it not possible to contact her and ask?
