Itzchak Aloni (top) and Menachem Oren during the 1954 Amsterdam Olympiad. From the "Portraits of Chess Grandmasters" collection by Phokas Fokkens. Credit: The National Library of the Netherlands' online "chess and draughts" collection (http://www.kb.nl/vak/schaak/intro-en.html).
From the same source as in the previous post, come the following two portraits. The small -- but high-quality -- online collection of the National Library of the Netherlands (see link above) is well worth a visit.
