Demonstrates how the SEC used enameled signs to convey instructions to passengers and confirm the advice of the conductor.An enamel sign with black lettering and border line on an off white background. The enameling is stained due to rust. The sign reads "To stop Car pull left hand cord ONCE". Where the enamel has been chipped, an attempt to disguise the damage has been made with paint. The reverse has been enameled in a mixture of black and white, but this shows signs of chipping and rust damage. Two holes have been drilled in the centre of the LH and RH edges to enable the sign to be attached to the tram car. The reverse shows signs that the enamel has been marked prior to firing as the sign rested on a framework which removed the enamel surface, allowing lines of rust to form.tram signs, tam car signage
