Bronze art stamped on top back. B. Altmans stamped on bottom back. Bookends shaped as indians.

Purchased at a garage sale complete Singer Treadel Sewing Machine with accessories and instructions.  Would like to sell for 300.00 obo.

I also have another painting. It's called Cranes In Flight. Size is 34 x 42. Pictures below

I don't know much about this item, but a chinese man told me it may be real ox bone and that underneath it reads qian long and maybe from early 1900's.  Any information would be so appreciated.  I may wish to sell at a later date but I have no idea if it is of any value.  I don't know who is the statue of, artist or value.  Can you help?

        This is an old Thomas tea cup, saucer, and pitcher set. I am not sure exactly how old it is. It now belongs to me. Before that it belonged to my mother and my paternal grandmother. She purchased them in 1914. How old they were when she bought them, I am not sure. The lid to the pitcher has a couple of cracks, but everything else is in excellent condition.
