Skizzenbüch military sketch book printed in 1942 copied from artwork by Hans Liska. There is a paper included that says "in memory of our service together" which indicates the book was likely a gift from one of the photographed pilots to the others. The book is in decent condition, showing a little wear and tear, the worst of which is on the edges / corners. There is a rip in the cover and some paper missing on the spine, which has some old tape on it to hold it together. The artwork mostly focuses on the Luftwaffe with a few other random sketches and water colors. It measures about 12" by 8".
