Country Codes by Billy Harkcom

A self initiated information graphics poster (600x800mm) titled "Country Codes". The idea came about after looking up a telephone (Subscriber Trunk Dialling) code to find out which part of the country the code covered and realising I could map the whole of the UK the same way.

After cross referencing around 610 different area codes and adding graphic rings to help depict larger cities based on size/population, here is the result. Hope you like it!
