The Oakland Athletics celebrated their 50th Anniversary in Oakland throughout the 2018 season, which included appearances by A's alumni, special promotions, events and giveaways. The A's created a special 50th anniversary logo to commemorate this important milestone. The logo emphasizes the team's connection to Oakland through the use of the Oakland tree and city skyline. The logo's shape is inspired by the iconic Oakland Fox Theater's marquee. The color used in the number 50, Oakland tree, roof tops of the federal buildings, and logo border is a special 50th anniversary gold. The team wore a modified version of the logo as a patch on the sleeve of home and visitor A's jerseys during the 2018 season.
