Poster advertising Exide Batteries, featuring the Moorside Edge Transmitter.

Poster reads: "The North Regional Station Moorside Edge uses Exide and Chloride Batteries for Power & Purity. Use them on your radio. We stock all types – get them from us."

This poster hung in Lloyd & Lloyd, a radio shop in Newport, South Wales for 60 years. Originally an ironmonger, the proprietor became interested in radio and diversified first into selling sets and later building their own. The founder’s son remembered his father placing a horn loudspeaker outside the shop to broadcast news updates of the General Strike in 1926 to passers-by.

The poster features an image of Moorside Edge Transmitter. Moorside Edge was the third in a series of high-powered regional transmitters built by the BBC to improve national radio coverage. Situated in the Pennines near Huddersfield, the station broadcast the BBC Regional Programme from 17 May 1931.
