There are red ballpoint pen markings on pages 5-19 of the 2020 edition. There were also pencil markings, but they have been erased with an eraser. Traces may remain in areas where the pressure was strong. I did not find any noticeable markings on other pages, but since this is a visual inspection by an amateur, there is a possibility of minor oversights. Please understand this before purchasing.
