Thanks for the information mariok54, it was helpful!
Do you know what it is made from?
It's my best guess that it's some type of Earthenware Clay Pottery (I don't know exactly) with an over glaze applied.
Although, I do find it interesting that the other plate I found online (Blue & White version with some variations - See link below) has the exact same US Capitol transfer on it in the center of the plate but it also has the maker initials of BBVF and their seal or Hallmark/Emblem. I wounder if that plate was a later version of this plate with the makers marks. I also wonder why the plate I have has none of these types of markings?

Thanks,
