The Miami Marlins compete in Major League Baseball as a member club of the National League (NL) East Division. The franchise was created in 1993 as an expansion team, playing as the Florida Marlins in Miami, Florida. The team officially changed their name from "Florida" to "Miami" in November 2011 following an agreement between the club, the city of Miami, and Miami-Dade County, who owns the team's new ballpark.
The team currently plays their home games at Miami's Marlins Park (2012-present). Before that, they played at Hard Rock Stadium (1993-2011).
The Marlins have won two World Series championships in the team's history, against the Cleveland Indians in 1997 and against the New York Yankees in 2003. Those are also the only two years that the Marlins have won the National League championship. In an interesting piece of trivia, both years that the Marlins won the NL pennant and the World Series, they qualified for the playoffs as a Wild Card team, making them the only team to win all their championships without ever having won a divisional title. They are also the only team in Major League Baseball, the National Football League, National Basketball Association, or the National Hockey League to have never lost a playoff round in the team's history.
Note: Be aware that in the early years baseball teams used pennants rather than flags, and a host of manufacturer's variants of these pennants and later fan flags were marketed for the Marlins and their fans. They include flags, banners, and pennants too numerous to all be shown here. Randy Young, 2 May 2019
The official flag of the Miami Marlins has likely changed recently, as the team adopted a new official logo and a new cap logo beginning in the 2018 season. As of May 2019, however, all of the flags currently for sale on the team's official website still incorporate the previous logo designs.
The most recent official flag features the team's official logo centered on a black field. The logo shows a white capital "M" outlined in orange and teal above the word "MIAMI" in smaller, white, capital letters. A marlin fish can be seen jumping from behind the large "M." The fish is orange on top and teal on the bottom, with a black stripe going down its side.
Another official flag of the Miami Marlins shows the team's previous cap logo centered on a field of orange, white, teal, or black (there are photographs online showing all four possible field colors). The cap logo removes the word "MIAMI" from the official logo, but otherwise remains identical. Randy Young, 6 May 2019

A number of commemorative flags exist for the New York Mets and their fans. Most common among these are the pennants that are awarded to the teams that capture the American League and National League championships, as well as the winners of the annual World Series between the two league pennant winners.

In Major League Baseball, a team that wins their respective league championship prior to reaching the World Series is said to have "won the pennant." This refers to the original reward for said team, which was the authorization to fly at their home field a pennant denoting the team as the champions. This tradition continues today, with teams that have "won the pennant" flying at their home stadiums pennants representing their historical championships. Randy Young, 19 May 2019
