The Giant Monopoly® Project
The Play Money
The paper game-money was a little harder, but once again luck was with me. Hasbro (who now owns Parker Brothers) has a Monopoly web-site and they (at that time) had made available PDF files of the Monopoly paper money so intrepid Monopoly players who ran out in the midst of a heated game could print up more. So I downloaded these, made a few digital adjustments and printed page after page of super-sized money. This took several weeks, spending an hour a day or less.
