Hi Mark -

Here are three glasses from Harold's Club. The one on the left is about the same size as yours - 3" across - and I think it is for mixed drinks - like Manhattans. The second one is only 2" across and I think it is a Cordial glass - for a Sherry and such. The one on the right is only 1 1/4" across and is probably an aperitif glass. But then, what the heck do I know - I grew up in a place called Okie Flats....
