vintage tile tableau

Description

Beautiful vintage tile tableau consisting of 6 tiles, 1950s-1960s
2 men against a black background
The men both have a moustache and one of them has a turban.
It is an oriental scene, probably Turkish, African or Arabic
Perhaps someone can see from the style of the turban which country it is.
Beautiful bright colours in enamel paint. The silhouettes as well as the signature at the top right are outlined in white which gives a special effect on the black background.
It seems as if the men are drinking some kind of tea or consuming something else.
Unfortunately the signature is unclear to me.
The 6 tiles are glued on a plywood wooden plate
Everything in a good vintage condition
Dimensions: 110 cm long, 48.5 cm wide and 2.2 cm thick. The weight is 11 kilos
