Illustreret Tidende. This illustrated journal was published from 1859 to 1924. There is an alphabetical index to the first 15 years and also a "Topographical Index". For example, a search on the city of "Ribe" in the Topografisk index lists illustrations of the church, streets, and buildings, etc. for Ribe. Select one of the articles and click on the title. Then click on "Denne side I PDF" to view that particular page.
