"Rupp's Skizzenbuch" is the journal /sketchbook of Unteroffizier Gerhardt Rupp from Jasta 77. Rupp is a character from Jack Hunter's novel "The Blue Max" and this journal re-tells the Blue Max story from his unique vantage point. The sketchbook will be published chapter by chapter as an online serial, bi-weekly starting January 1, 2018 and will run right up to Armistice Day on November 11th. Here is a preview of what an "online serial journal" will look like.
