Historic Art Print "Battle of Bunker's Hill" Wood Americana Vtg Sepia

I believe this is a decoupaged art print on wood. It does have an aged, sepia look. This piece is the "Battle of Buker's hill" by John Trumbull, Yale University Art Gallery. It is 20" x 16", or 18" tall if you count the hangers on top. It does have several scratches from age and wear. There are also marking and whatnot on the back of it. There is a bubble in the print. Please see pictures. It is a heavy piece at 4 pounds.
