Volume 1 Issue 1 of the "Summer Edition" of Treasure Chest issued in 1966. It is my understanding this was available by subscription only and there were six issued throughout the summer.
This issue has a stain on the front cover approx., 1/3 from bottom and to right of center. The crossword puzzle, etc, on the inside of the front cover has been completed and the puzzle on the inside back has as well. In addition, there is writing at the top of that page. Otherwise, the book is in very good condition. Curiosity around potential value?
