CAN ANYONE HELP WITH ID ON THESE BEER BOTTLES? Africa maybe

I found some amazing wood carvings that my college professor (seen at the end of the table) left me. I am trying to locate the origin of these carvings. They were brought back from a mission trip trip he took in the 1950s or 1960s. Can anyone help me I'd these beer bottles seen in the photo? And date them by chance. Thanks in advance for your help. If anyone wants to see the sculpture carvings I can post.
