old cast iron fireback salamander fireplace plate

Hello, I am selling the magnificent cast iron fireback shown in the attachment. It is a 20th century production, featuring a salamander, the emblem of Francis I, and crosses/ermines, the emblems of Brittany. The fireback measures approximately 57cm wide by 52.5cm high and 3cm thick. It is in good general condition, with signs of use and dirt, and may require cleaning.
