Flue covers were round plaques used to cover the unsightly hole
that was lefted in the wall when the heating stove was taken out of the home
and moved into the barn during the warm weather months.
The hole in the wall was due to the stove's exhaust pipe had to be inserted
in the round hole in the wall that connects to the chimmney..
The long chain allow the hanging nail to be above the picture & hole
Note: how the back of the Flue Cover has a round contour
as if it was an attempt to fit into the wall hole a litttle bit.
Today, they are lovely reminders of the past to hang on a wall.
