they measure 36" Long and are 16" At Widest

All the Brass Tack decorations are solid brass

The US Rosette is also solid brass and measures 1 3/4" Diameter

They have wear - even a mouse or other rodent has chewed on the back side of one

They have been had oil or leather conditioner of some sort applied
