According to the newspaper, the game will be played by the (New York) Giants and (Boston) Red Sox; however, the players' uniforms have the team names "Giants" and "Cubs". This would be impossible in the real World Series, as the teams with those nicknames are both in the National League.
The call letters 'KWB' on Porky's microphone are readable when looking from in front or from behind - in one angle, the letters should appear reversed (as if looking at them in a mirror).
When looking into the press box from outside, to Porky's left is some kind of radio equipment with a dial, a coil, and some buttons on it. To Porky's right is a typewriter. When the press box is shown from the inside, looking out, there is an adding machine to Porky's left, and nothing to his right.
The onscreen copyright statement incorrectly lists the year 1940 with Roman numerals "MCMXXXX" instead of the correct MCMXL. Four of the same letters in a row is not permitted in the rules governing the Roman numerals.
The radio station call letters KWB would only be used west of the Mississippi River, not for a Giant-Red Sox world series which would take place in the eastern United States.
One of the subheadings in the newspaper at the start says 'In case of a tie, duplicate awards will be made'. In a game of this nature, ties would not be allowed - they would play extra innings until one of the teams won.
According to the date on the newspaper, the game is being played on August 20, 1940. In 1940, the World Series was played from October 2nd to October 8th.
