Left) Typical 1871 shape; kind of an Apple Green
(Center) Unembossed, Ice Purple with fantastic bubbly swirls
(picture doesn't show it well - I don't think its a Hemingray...)
(Right) 1871/1893 squared off dome; typical "Aqua"
Update: The middle one is a CD 120.2 "No Embossing" style (not listed in the Price Guide)
