Orientalist watercolor landscape Morocco Marrakech characters Guedeler nineteenth

Lovely oriental watercolor of a desert landscape in the Maghreb, certainly in Morocco near Marrakech, with characters walking towards a village, signed P. of Guedeler, late nineteenth and early twentieth centuries of time.
This watercolor is in good condition and frame. It is under glass. It is signed lower right.
A note: the paper is slightly yellowed (barely visible), see photos.
