According to Amrouche, in the catalogue of the exposition, it's not possible, due to the too close interactions between the two populations, to attribute to Losso or to Lamba alone the items so he choose to call this corpus of objects "Lamba / Losso". He pointed also the fact the corpus itself is splitted into two main styles: one, more common, extremely geometric and stylized and the other more naturalistic.
I had in my collection five single figures and a couple (from the Amrouche exh.) but I've also had the luck to find recently two other examples, one single figure (26, 5 cm) and a couple male-female (29 and 30,5 cm), both very old, with a very dense patina, heavy and hard wood made.
