Mr. Met is the official mascot for Major League Baseball's New York Mets. Mr. Met first appeared in 1963 as a cartoon drawing in programs. When the team moved to Shea Stadium the following year, he came to life in the form of a costumed mascot -- it's believed he was the first mascot to appear in human form in Major League Baseball. Mr. Met is a man with a large baseball for a head. He can be seen at Citi Field during Mets home games, has appeared in several commercials as part of ESPN's This is SportsCenter campaign, and has been elected into the Mascot Hall of Fame. In 2012, Forbes Magazine listed Mr. Met as the number one mascot in all of sports.

After that time, he was not utilized in their advertising and he remained absent for almost 20 years.
