Chanda I would think that the Arby's Currier and Ives glasses were screen printed, as that is what I understand was the general method used in the 1970's to do the graphics on the glasses. I do not know for sure who made them - I can say that I saw a box set just last week in Lafayette, IN of Currier and Ives glasses that were the same size and style of the Arby's glasses - there were 4 in the box, they were done by Brockway Glass Company. But these were NOT Arby's glasses, but as I said the same size and style of glass as the Arby's glasses. I will look in my copy of the Chase & Kelly Collector Glasses book - I know the Arby's glasses are listed, I really doubt that the maker is mentioned but I will check. If I find any information I will post it on this message board. The glasses I saw were like the ones on this link
