I need help on this marked Imperial Glass piece. I think it is early in age (1940s/50s?), and I think it goes by the name of just Grape or Heavy Grape. I'm not sure of the color (iridescent vs. carnival--what would color actually be)? I also think it looks like a sherbet and not a wine glass, but I can't find it as either a wine goblet or sherbet either one. Any help in clarifying exactly what this pattern is called, whether it's older Imperial or not, and whether it's a wine goblet or sherbet would be appreciated.
