here are 2 more pics. .in a jpeg format.
I don't have a scale but it is really light.
Mart / KC- I don't know her ancestry, and yes it looks just as dark yellow as the pics. I laid it next to a ruler. hope this helps.
IPcress /Ghopper- neither of you have to "eat your shorts". but I will take that as you don't believe it to be Ivory, got it.
but do you have any useful information? ie. Era? whom is on it? who made it?
