Here are some of my proposals. Instead of creating a separate icon / typography combination, I've created an all encompassing logo / unit. One that can be used for additional elements just as watermarks.
The logo is 100% vector so will scale well to any size, and works well in full colour, B&W and on coloured backgrounds if needed,
It would be my pleasure to work up any variations so please do say. I look forward to your comments or thoughts.
Thank you very much for your entry. Your design was very elegant and I appreciated your discussion points. I never expected the decision to be so difficult!
