Sign is made out of a heavy metal, and has a copper top plate. The construction of this sign is identical to a early printer's block, only it doesn't have a wood block backing.
Has some corrosion which I haven't attempted to clean. A nice early Hoards Dairyman sign.
Measures: 18 1/2" Wide x 10 1/4" Tall. If you have any questions feel free to ask.
