This is a 30-second black-and-white television advertisement from 1959 for Cadbury’s Crunchie chocolate bar.

Please be advised that this video contains strobe effects and flashing lights

A pan of the sorting rooms shows women sorting the cleansed chocolate in preparation for blending. The kernels are then taken to the mills where they are ground into a smooth liquor.

The way that Cadbury advertised its chocolates has changed over the years, but a constant theme of their advertisements is romance.

The Crunchie wrapper in this ad shows it to be a Fry’s product and has no reference to 'Cadbury’s Dairy Milk’ at all.
