The logo for the Montreal Expos is made up of a stylized "M" for Montreal, with a lowercase "e" on the left for Expos. It is italicized to represent forward movement.
On September 5, 1968, the National League announced the name of Montreal's expansion franchise as the Expos. Their logo was unveiled on January 15, 1969. The formal definition of the logo is that it incorporates an "M" and an "e" for Montreal Expos.
There are also other speculations about the meaning of the logo. For example, some see a lowercase "b" on the right side of the emblem. This leads to supposition that the letters represent Montreal Expo baseball. Some view the "e" as a "c" instead, therefore reading it as initials for owner Charles Bronfman. The initials of "e" and "c" could stand for the owner's daughter, Ellen Bronfman. Another viewpoint is the white part of the logo represent an "l", leaving the initials "elb." This is said to reference Expos League Baseball.
In the late 1980s, the club gave a somewhat definitive answer on the subject off its logo, stating that it is comprised of three letters: a capital "M," lowercase "e" and lowercase "b." These letters stand for Montreal Expos baseball. Some question the validity of this statement, however, as it was released 20 years after the team's inception.
