Issued in 1970, this commemorative set from Norway (Norge) marks the 900th anniversary of the Diocese of Oslo (Oslo bispedømme 900 år). The 1.00 kr stamp in blue and black shows a church silhouette and figures representing the people served by the church through generations. The 70 øre stamp in red and black depicts a church spire and builders at work, symbolizing the spiritual and architectural foundations of the diocese. Designed in a modern minimalist style, the issue honors nearly a millennium of Norwegian Christian heritage and ecclesiastical history.
