Cor van Weele from Amsterdam was the principal photographer of jewelry from the Martinshof Collection. He also designed these two covers for my father's production of the Goldsmith Magazine De Goudsmid en zijn Kunst ("The Goldsmith's Noble Art") later renamed Eloy after the Patron Saint of the goldsmiths' guild "St. Eiligius". Text was in Dutch, English, German and French. Only two issues ever were published, probably due to financial restraints.
