There are proper billboards in Liberia, the glossy kind with models and slogans, but hand-painted signs like this are still the norm along the major roadways. Many of them are health focused, telling passersby to "wash your hands after pupu" or, like this one, to vaccinate yourself and your children against major preventable diseases. Notice the much nicer Omega Insurance billboard in the back?
The "Welcome to Bong County" sign is an awesome metaphorical testament to Liberian reconstruction. You have the boatman sailing the Liberian flag with an oar of Reconciliation, his passengers holding signs for "Peace," something too small to read, and "Truth." The center of the shining sun is the Bong County flag and in case you missed the metaphor, we see that Bong County is indeed "sailing forward to a brighter future for Liberia." I'm glad they didn't paint any sharks in the water.
