Each measures approximately 10 ½ inches long by 14 inches tall. I believe the three volumes represent a complete set. All are lightly dirty and dusty throughout their exteriors. All show moderate surface scratching, scuffing and wear throughout from age and use, especially along their exterior sides, corners and edges throughout. One has a 1 ½ inch long section of denting along the top left corner and edge. One is sealed in what appears to be original factory plastic. The plastic is in poor condition with heavy discoloration, tearing, scratching, scuffing, missing sections of plastic and wear throughout.
