Does any one know anything about these type of glasses? My Grandmother had these, and I remember drinking from these same ones back in the 60's. There are 6 of them and various colors. My mom seems to think they were promotional glasses that came inside boxes of laundry detergent or something? I have not been successful in locating any info on them since there are no markings on them. I am very curious about them, if anyone can help, all is appreciated.
Thank you!
