Super rare Sound Sparton single sided 20\" porcelain sign, no touch up\'s ,has chips mainly on outer edge.
I have seen the Sound Sparton railroad signs, but this is the first School House DriveSlow sign( auto related)I have ever run across.
Sparton was a brand of automobile horns, and thus people called a horn a \"Sparton\" back in the day.
Great piece for an advanced sign collector,vintage car garage or museum.
