The Council for British Archaeology has been around for years, so by me changing the name completely to 'Fossil' this may loose some of its current customers. However, i do like the name Fossil and may use this for the new identity of the Young Archaeology club.
I am shortening down the name to 'British Archaeology'. This way the current customers will still recognise aspects from the previous brand and the new will be drawn into a more modern and exciting brand. Both sides win.
As for the logo design i will bring together the name 'British Archaeology' and the spiral symbol to create a solid identity.
