Best vintage Stocks & Bonds, sealed, never opened 3M bookshelf board game

best Stocks & Bonds, the game of investments, stock market game for investors and speculators of all ages and incomes. A 3M Bookshelf board game.

The copyright year on the box is 1964, however by the design on the back of the box looks like the 1972 edition. It is sealed in original shrink wrap and I haven't opened it to check if a different year is on the inside.

Teens and adults. For 2 to 8 players.

Still sealed, great find from a recent estate sale in Ohio.
