The Boston Celtics have an iconic logo that is recognized around the world, particularly in relation to the Boston Celtics Wordmark logo. However, they also have a long history of alternate logos, which are just as recognizable to many fans. From their classic shamrock design to their more modern “Lucky” leprechaun logo, the Celtics' alternate logos showcase some of the most beloved designs in sports branding.

The first official Boston Celtics alternate logo was introduced in 1992 and featured a green three-leaf clover with “Celtics” written across it. This design was used for various promotional materials and merchandise until 1998, when it was replaced by an updated version featuring a four-leaf clover instead of three leaves and larger lettering for "Celtics." The team kept this look until 2002, when they changed it up again with another iteration featuring two interlocking Cs inside a basketball shape surrounded by stars; this one lasted until 2009 before being phased out once more in favor of something new: The Lucky Leprechaun Logo! This version features an anthropomorphic leprechaun character holding up his lucky four-leaf clover while wearing traditional Irish clothing such as a hat, coat, shoes, etc., against a backdrop made from a Celtic knotwork pattern – making him both instantly recognizable and unique at the same time!

Overall, these various iterations show how much thought goes into creating a compelling brand identity for professional sports teams like Boston Celtics, who need to stand out amongst the competition so that fans can easily recognize them wherever they go or whatever sport is watching! With its timeless designs spanning decades now - each one showcasing different aspects of the team's culture & heritage - there is no doubt why so many people still love these alternative looks today, even though the original has become an iconic symbol itself over the years too...
