One Auction down, one to go. I was the lucky buyer of this beautiful piece of Arabia Finland. A huge (33cm) platter by Gunvor Olin Gronqvist from the "Fructus" series. Gronqvist started with Arabia in the mid 1950's - I think this design is from just after that date - which pre-dates patterns like Valencia.
You more commonly see the brown and black version of this design, and this intensely dark and very saturated violet-blue is much rarer than the brown. Apparently there is a lighter blue as well but I have never seen that.
