The booklets "What does the world consist of?" (in English) and "Woraus besteht die Welt?" (in German) provide in a compact form with many coloured pictures and not too much text informations on the present status, theoretical foundations, open questions and the history of particle physics. You can obtain these booklets from Lulu, where you can view some pages.
