On the attached PDF, the original logo is shown at the bottom. That logo is well-known but has the outline of a mountain above the words. This does not represent the organization any longer. I sketched up a few ideas. We would take the same font, letter style, and add to it a water well possibly coming out of the "L" in "Last".
I'd also like to play with the idea of putting an outline of Liberia in the logo somewhere (as I've sketched or similar). Finally, I'd like to consider "filling" some or all of the letters with an aqua blus, representing filling the logo with water.
