"Design played a crucial role in promoting social progress and technological change across Britain between 1930 and 1960. The commercial poster reached cultural maturity during this period and became the most eloquent of the mass media. From the 1930s onwards the Post Office became a leader in the field of poster design, commissioning some of Britain's best artists and designers." http://www.postalheritage.org.uk/page/designsondelivery
