African expedition

This series includes at least 18 references in at least 3 colors. What seems to be missing in this shipment is of course the presence of animals as well as a small hut.
The small size of the car and the tent suggests the possible existence of a diorama.
As for the brand, no indication allows its identification. The size, the style, remind us the Café Mexiq or in Cooperative, but nothing is sure yet.
