A few letters and postcards remain that Abraham Beem (whose name in hiding was Bram) and Eva Beem (whose name in hiding was Lini) sent their parents in hiding from their address in hiding. A Sinterklaas rhyme in the autograph album of Eva Beem (dated 5 December 1942), a geography examination and two postcards, sent from Westerbork on 21 May 1943, remain as well.
