Proxima Centauri Interplanetary Bowling League

The Proxima Centauri Interplanetary Bowling League (and their marching band) was a bowling organization in the Federation, home-based at Proxima Centauri.

Personnel from the Sirius Cybernetics Corporation signed a certificate naming Ira Graves as "humanoid of the year" in gratitude for his contributions to the league and band. (TNG: "The Schizoid Man")

The league's name was only visible on a piece of background artwork decorating the set of Graves's office.
