Economy pack of a three month course of Nervone, in three boxed bottles, one for each month. Claimed to be 'the new nerve nutrient' that 'builds up nerve power', by New Era Laboratories Ltd., London, 1924-1949.

Nervone was advertised as a ‘new nerve nutrient’ that ‘builds up nerve power.’ It was made by New Era Laboratories Limited of London. The tonic was typical of medical preparations sold ‘over the counter’ in chemists across the country. The pills were dissolved on the tongue three times daily to ‘reestablish that happy state of Nerve tranquility’. It was suggested adults take two tablets and children take one. A three-month course of Nervone came in an economy pack of three boxed bottles, one for each month.
