Hi, i have had this for years and never known what it is.
It's 10.5" tall and is a pale mint green in colour. The glass surface is a buff or frosted effect.
The base has no pontil or ground in any way, just moulded looking.
Its signed what I think is a 'M' in a circle then 466/078CCAA1980 , it looks a bit Scandi to me but not sure.
Thanks for any help, Wolfie
