Vintage Cast Iron Wall Plaque? Colonial Women Scene SEE DESCRIPTION For Sale

I’ve seen ones 95% the same as this one labeled as solid brass. I’ve also seen ones made of ivorex that are nearly identical. I’ve seen these labeled as stove plaques and wall plaques. There are no makers marks that I can find. It’s definitely metal and I’m fairly positive this is cast iron and not brass, however this is the first one of these I’ve come across so make up your own mind as to what you are purchasing as I personally have no knowledge on this piece. 9”x7” weighing 3lb 6 oz
