Up for your consideration is this antique fireplace mantle intricately carved marble keystone. This keystone dates from the late 1850's thru the early 1860's.There are just a few minor blemishes (shown in photos) and some early brittle paint residue that can be easily cleaned off if one chooses to reinstall on their period mantle. I have left the original patina in case the buyer chooses to hang as an art piece. It measures 10 13/16" in H, 12" in W and 3" in D, and weighing just under 10 Lbs is as finely carved example as you"ll find. I will have 4 keystones listed for sale. Please view all photos carefully before bidding.
