Large old all metal tea box for shipping, and store display? There's just faintly visible lettering TEA to the plain metal front of the chest, any other markings were painted over many years ago.
The box measures about 16 1/2" tall x 15 1/2" wide x 15" deep - bigger than a breadbox, sized like a general store storage cabinet / dry goods bin. It has a lovely antique industrial style look.
