Vintage Cadbury Milk Chocolate Biscuits 1954 Print Advertisment. This lovely vintage advertisement is from a September 1954 English Home Notes magazine. The advertisement is in very good condition and measures 16cm long and 23cm high. The Cadbury Biscuits ad needs to be cut from the front cover of the magazine as can be seen in the photos. A unusual and rare ad ideal for any Cadbury collector.
