'Best of British' (beef, cheese, eggs, mince) television commercial

Television commercial (30 seconds) promoting the "Best of British food". The advertisement features a narrator (out-of-vision) who begins "You'll find the best of British foods at Sainsbury's at some of the best of British prices". He then describes some of the products and prices with footage showing various British food products (for example a joint of beef being carved, a boiled egg being tapped with a spoon).

The following products are promoted:
Topside of Beef £1.86 per lb
Cheshire and Double Gloucester £1.08 per lb
Size 4 Eggs 29p per half dozen
Home produced mince 95p per lb

The narrator ends "For the best of British, good food at good prices mean Sainsbury's". The end caption just reads "Sainsbury's" with disclaimer "All items subject to availability".
