Well there are these three here........I have seen a photo of an amber version of the donkey with a group of animals on a Maltese website and in the group there was an MDG speckled rabbit with cane eyes . So the donkey might well be MDG too. The blue donkey has a much darker head than the main part of the body where the glass is at it thickest, the same goes with the penguin to the right which also has a gradation of darker blue to the head and lighter towards the base. I also have another similar blue donkey, where there is a variation in the blue colour . It could be that the donkeys have a lighter colour blue as a core. Both donkeys have 'battuto' bases. Cheers Mike.
