The £20 note, with a profile of Adam Smith on the back, is the second highest denomination note in value and the second largest in size (approx. 149mm x 80mm).
Denomination numeral - there is a large number 20 and £ symbol in the top left corner on the front of the note to assist easy recognition of its value; this negates the need for a specific symbol for the partially sighted. There is also a slightly smaller number 20 in the top and bottom right corners.
Unique numbering - a unique number is printed horizontally and vertically on the back of the £20 note. The horizontal number is in the bottom right corner and consists of multi-coloured letters and numbers, increasing in height from left to right. The vertical number runs down the left side and has letters and numbers that are the same height and colour.
Copyright symbols - the international copyright symbol is included on the front and back of the £20 note. This can be found to the left of the holographic strip on the front of the note and on the back under the words 'Bank of England.
Adam Smith (1723 - 1790) is one of the fathers of modern economics. In one of his great works, An Inquiry into the Nature and Causes of the Wealth of Nations
, Smith famously used the example of workers in a pin factory to describe the benefits created by the division of labour, and, as explained on the note, 'the great increase in the quantity of work that results'.
