Porcelain Bone Dish

Porcelain bone dish with no manufacturing information. I am not sure of the age, but I've had it about 20 years and it wasn't bought new. No chips, cracks or breaks. Several tiny dark spots in the finish that appear to have been fired in during manufacture. There is a tiny streak of misplaced paint. There looks like a tiny crack in the paint, but does not go through to the porcelain. Email for detailed photos of the condition. I need your zip code to calculate the postage.
