The General Post Office (GPO) was the postal system and telecoms carrier of the United Kingdom. In 1969 the GPO was set to be abolished and all of its assets transferred to The Post Office. This would change its status from a Department of State to a Statutory Corporation.

Going forward, The Post Office would operate a number of services which would be under the control of different departments. These departments oversaw the ownership and operation of telephone equipment, and the provision of banking and postal services. Together, these created a complex set of disparate offerings and a multitude of contexts in which to design for, with no governing design policy. In order to address this, Post Office engaged FHK Henrion in a three year consultancy service.

The outcome was a proposal by FHK Henrion to develop a visual identity and logo system for the four departments; Royal Mail, Post Office, Postal Services (Road, Sea & Air), Telecommunication & Data Processing and Banking services known as National Giro.
