DescriptionThe four-sided, internally illuminated square counter-top point-of-purchase display has reverse screen-printed glass panels in metal box on a circular stand.  Each panel shows a different wiring schematic for an auto's electrical system. At one time, it was at the Ashland Electric Shop in Ashland, KY--a distributor of electrical auto components owned by J&N Auto Electric in Sharonville, OH. Ashland Electric also offered training in troubleshooting auto electric problems and this sign was used as a training aid.
