1870 Flat Black Glass Bottle For Displaying Food Serving charcuterie Tray Decor

I believe this is an authentic 1870 bottle which has been artistically melted and formed. The two bumps on one side prevent food from sliding off, or flip it upside down and you have a nice level display shelf. Minor discoloration on one section as shown near pen in photo. I don't see why it couldn't be buffed out if this bugs you.
