The 1966 edition keeps the short and long game but removes the nominee game. Instead it offers the option of scoring by popular votes instead of electoral votes.
back of the box: new sheet is pasted over apparently.
back of the electoral cards mostly blue (1 of 5 copies only: rose/red)
back of the campaign cards mostly rose/red (1 of 5 copies only: blue)
side of the box (spine): mostly printing in Golden letters (2 of 5: beige/brown and quite hard to read)
