Marvin Gardens, the leading yellow property on the board shown, is actually a misspelling of the original location name, Marven Gardens. The misspelling was said to be introduced by Charles Todd and passed on when his home-made Monopoly board was copied by Charles Darrow and thence to Parker Brothers. The Todd board is on display in the Forbes Gallery in It was not until 1995 that Parker Brothers acknowledged this mistake and formally apologized to the residents of Marven Gardens for the misspelling.^[7] Another change made by Todd and duplicated by Darrow, and later Parker Brothers, was the use of North Carolina Avenue, which was substituted for South Carolina Avenue on the board.

Short Line is believed to refer to the Shore Fast Line a that served Atlantic City.^8] The B&O Railroad did not serve Atlantic City. A booklet included with the reprinted 1935 edition states that the four railroads that served Atlantic City in the mid 1930s were the Jersey Central the Seashore Lines, the Reading Railroad, and the Pennsylvania Railroad.

The Baltimore & Ohio was the parent of the Reading. There is a tunnel in Philadelphia (PA) where track to the south was B. & O. and track to the north is Reading. Perhaps this is a reference to that. The Central of N.J. did not have track to Atlantic City but was the daughter of the Reading (and granddaughter of the B. & O.) Their track ran from the New York City area to Delaware Bay and some trains ran on the Reading-controlled track to Atlantic City. This is covered in "The Route of the Blue Comet" published by the West Jersey Chapter of the National Railroad Historical Society.

The actual "Electric Company" and "Water Works" serving the city are respectively Atlantic City Electric Company (a subsidiary of Pepco Holdings) and the Atlantic City Municipal Utilities Authority.
