I've been holding off on posting this because I really don't know what it might be.  I am guessing a decorative back plate for something (wall sconce?/drawer?). Anyway, if you know what this actually is, please let me know so I can update the title and listing.

It is pale green, cracked glaze ceramic with the image of a female bust facing left and wearing a head scarf.  I am guessing at an age of around 1900, but not sure.  There is a central hole for a screw/bolt/whatever type of attachment you would put in front of it.  It measures 3-1/2" in diameter and is unbranded.  Looks like it was poured in a mould.  There is slight wear but I do not see any chips or cracks in the piece.  It should probably come as a set, but I only have the one, sorry.

I have tried to describe any issues with this item as much as possible.  I can post additional photos upon request and will try to answer any questions you might have that weren't addressed above.  If you want to purchase more than one item, let me know and I will wait until your purchases are complete, then I will send a single invoice with one shipping charge.
