Vintage 1960s Fairchild 'Moon Mission' Jigsaw Puzzle 750+ Pieces NASA Photos

Vintage 1960s Fairchild Brand Jigsaw Puzzle. Moon Mission showing the 4 major steps in the exploration of the moon. Official pictures of NASA. Interlocking cardboard pieces. 19x19. I believe that all the pieces are there but it only says over 750 pieces not an exact number? Puzzle is in excellent vintage condition. Box is starting to separate at the corners and some edges. Can be taped. There is also crayon marking on the inside lid.
