Here are 2 antique Danish language religious books by author O. Thune Jacobsen; they are: "Sandhedens Erkendelse" (Recognition of Truth: A Contribution to Clarifying the Logic of Religion) and: "Jesus and the Evangelists-the Differences of View in Matthew, Luke, and John, " 1911.
They are both from the same era (1911); the first has 117 pages and the latter has 194 pages.
They are both written in Danish and in very nice condition considering their age of over 100 years!
Let me know if you have any questions!
