This is an antique fireplace hearth protector from the Blink Bonnie inn in Gananoque. It is 47 in wide and approximately 1 ft deep. A fireplace screen would normally fit inside it. Also included is two brass firewood holders, complete with logs! There is also a few fireplace tools in those holders, again from the Blink Bonnie.
This is a piece of history from Gananoque.
