Student class report on "Charts & Graphs," full of charts and graphs

Presumed Western Pennsylvania, dated 1957. Black fiberboard notebook binder wraps. First 9 leaves each feature a different style of chart or graph related to textbook data, including "Net income levels - Civilian Dentists 1948." Many sheets of unused graph paper and two manuscript pages at the end with quiz questions like, "What is a chart?" Tidy and neat in multiple respects.
