The images contain a sample page on the left from Alban Douglas' book first copyrighted in 1966 One Hundred Bible Lessons: God's Answers to Man's Questions. On the right of the two large images are a sample page from two different booklets from the series Theological Studies by Peter Ruckman copyrighted in the 1980's. No mention or credit is given in Ruckman's Theological Studies for Alban Douglas' work. We are presenting only a sampling of what we found in Ruckman's Theological Studies series. Many more examples could be given. Is this plagiarism? You decide.
