Fun parfait glasses?

I only use these for special occasions. Not sure what they are called or when they were made. My guess is 1950's-1970's. My husband acquired them when a tenant passed away and these were left behind by family. They have alternating silver shiny metallic and etched lines from top to bottom. The base is red with a silver metallic border. They are approximately 4 to 5 inches tall and hold the perfect amount of dessert after a big dinner. My brother refers to them as carnival glass, and while I know nothing about glassware, I don't think these quite fit the criteria. In any event, dessert always tastes so much better when served up in these cute little glasses.
