Hi All !
A couple books from my small collection:
...the book from bottom left corner is "Dzieje Anglji" from 1940 with 1st Polish Rifle Brigade's stamp and "Basic English For Polish Students" (right bottom corner) also from 1940 - with the book owner's signature "Dr.med. MOŹDZIERZ Janusz Polish Forces" - probably ppor. dr Janusz Moździerz from Polish Carpathian Lancers Regiment.
