Vintage Bookends, Plaster, African/Egyptian Style Bust, Burnished Bronze Finish

I can't find much information about this set of bookends but they appear to be African or Egyptian. The material looks to be plaster given the small sections of wear (see photos). They are not metal unless parts of the busts are mixed mediums. They are quite striking and very detailed. Please see photos are description. Sold as is. Each weigh a little over 3 lbs. before packaging and solid. I will continue to research and update the listing accordingly. Each measure 7 1/2" x 4 1/2" x 5 3/4". I'm offering free shipping as the weight is more than the platform shipping weight of 5 lbs. Therefore, it's easier to calculate shipping into the list price.
