(Photograph) - Celt up: for teachers seeking materials to support history for eight to 11-year-olds, these Celtic warriors appear courtesy of a company called Key Stages, which has produced four A2 laminated posters each with separate teacher’s notes. As well as the three tribesmen on the warpath shown above, there are similarly vivid images of Roman soldiers, a Saxon helmet and a Viking longship. The material has been carefully chosen and uses authentic sources and replicas wherever possible. The set costs Pounds 17.02, plus Pounds 2.98 VAT, from Key Stages, POBox 78, Orpington, Kent
