Hi Stephanie, and welcome to the Forum! I hope you will enjoy having a look around, and please feel free to ask any questions that come to mind.
My first reaction to these glasses is how beautiful they are! Five different colours, and such a lovely design -- if they were mine, I would very definitely keep them for special occasions and meanwhile give them pride of place where they can be seen and admired.
Would you have any idea what period they might have been on board? There were certainly none like these during her final decade, unless they were used only by very special people for very special occasions.
