Baboon in sunglasses

[Pole Pole]

While my wife and I were stalking a buffalo in the Selous she lost a pair of Costa sunglasses with turquoise rims and gray lens. Where we stopped the hunting car to start the stalk I notice some monkeys and one baboon. They were expensive so looking too recover them. We looked high and low but never found the sunglasses so I deducted that baboon made off with them. Being the only baboon in the Selous, maybe in all of Africa, sporting Costa sunglasses there must be some sightings. Please post any sightings or information you may help in my efforts. Thanks in advance. Pole Pole
