Vintage 1968 3M Breakthru Abstract Strategy Board Game Complete Used Battleship

Here’s a complete vintage Breakthru board game from 3M’s iconic bookshelf game series, circa 1968. Packaged in a slipcase styled like a hardcover book, it shows expected signs of age: light shelf wear, a tape mark on the box, and softened edges. Inside, the board and all gold and silver playing pieces are in excellent shape. Game components remain intact, and the instructions are present. Designed as a tactical naval-style strategy game—one player leads a gold flagship fleet attempting to flee blockade, the other controls silver ships trying to capture it—this classic challenge still delivers deep gameplay.

Breakthru was part of 3M’s renowned bookshelf lineup from the 1960s, now highly collectible and no longer in production
