I have a small but to me, very precious collection of Marcolin / FM Konstglas/ V.Nason glass.
I sold the blue bird because I perceived it as an 'Intruder' in the collection. But as often is the case, I now have 'sellers remorse', because on reflection, it was a very pretty bird.
It showed a level of artistry and production technique that should have been appreciated for what it is and not what it was thought to be!!
I am questioning my own values more and more these days, and am trying to collect what pleases me as much as what is considered valuable.
Your little duck looks like quite a cutie Stew, and even though the base may not be polished, if you like it, well,the base won't show on display.
