African Paintings signed Tshibanda

I've had these 2 African paintings for a long time. I bought them in a charity shop, and they are not in very good condition. Painted on canvas stretched on a frame. I've always meant to get them framed and hung on the wall, but never quite got round to doing them. My favourite is the one with the tree. Probably painted for tourists, in the last century, maybe mid century. The are both signed Tshibanda. There is a Senegalese artist with that name, but from what I have seen of his work, these are not by him.
