Liberia is unique among countries of the world, much less African states, for being home to six separate writing systems for the transcription of local languages. Bassa, Vai, Mende, Loma, and Kpelle have all been codified into their own writing systems since at least the mid-19th century, on a continent that has only a handful of other instances where languages adopted writing systems.
A Bassa Keyboard. Seriously.
A Table of Vai Syllable Symbols.
I have seen no signs, billboards, advertisements, newspapers, or handwriting in a native writing system in any corner of the country, although these have been reported at least as recently as the 1980s—missionaries from the Doe era report Vai and Bassa people using the scripts for communication. In present day Liberia, I really think the main concerns is learning professional English and writing skills to get a job. These scripts are beautiful, but sadly have faded from whatever erstwhile employ they regularly enjoyed. Today, the Bassa language is generally transcribed in the phonetic alphabet also.
