Formal and Informal

Source: Sarah Aloni's collection

From Sarah Aloni's collection, we have also these interesting photos of chess concentration in both "informal" and "formal" dress -- "formal and "informal" for a kibutz member, that is.

I do not recognize the player (can someone help?). But Mrs. Aloni notes photos were taken during the kibutzim's movement yearly chess tournament, in the Matzuvah kibbutz, ca. 1960.
