The rules to this old small box edition from Parker Brothers states: 'A short game of Monopoly - Sixty to ninety minutes of the fun and pleasure of the regular game of Monopoly.' This game may have been sold separately from the game board because the box of deeds, money, and tokens is too small for the board. The back of the board does have a sticker stating it is for the 'Popular Edition' but looks identical to the edition printed today.The rules state that this edition is different from the regular edition in three ways: 1. 2 title deed cards are dealt to each player before starting the game. 2. It is only necessary to have 3 houses built on each lot of a complete color group before a player may buy a hotel. 3. The game ends when a second person goes bankrupt. (The first person to go bankrupt retires from the game earlier.)The richest player wins! - BoardGameGeek
