Here is a couple of parrots for the zoo.
Both are by Bayel, France. The one on the right has an acid mark on the base. The one on the left has a transparent plastic sticker. Both are contemporary. I do not know how far back 'contemporary' goes with the one on the right, but the one on the left was made within the last 5 years. There are other critters in Bayel's line, but I only have these two, as both of these have uranium glass in them. They are also rather expensive, about $200-250 USD. You have permission to use the image.
