These wonderful vintage Art Deco bookends are most often called Speed although one maker called them Dancing Girl. The image is a classic Art Deco dancer who looks like she is about to take flight. They are made of white metal or spelter and painted green. The maker is LOB & Co. They are not the maker most often associate with this image and I have not been able to find out anything about them.
They measure about 6 1/2 inches by 6 inches and they are in very good condition with some chips and wear to the painted finish.
