Lee vs Grant A Civil War Game 1965 Rare Educational Vintage

Description

Lee vs Grant A Civil War Game 1965.
This game was created in 1965 as an educational game by Stone Enterprises.
The game has a 27" x 22" game board with all of the states, at the time of the civil war.
There are 12 Union soldiers and 12 Confederate soldiers. There is a General Robert E Lee figure and an Ulysses S Grant figure.
The spinning dial has some wear and tear, mostly from bugs it looks like.
The instructions are included and the dice.
There are gray (17) and blue (18) action cards that contain game play directions and Civil War facts.
The box top has torn corners but pretty good condition for its age.
I have never seen another version of this game. It says Patent  Pending, so I believe ot is a rare game.
