This is a very rare and hard to find Discraft Ultra-Star custom print. The Ultra-Star is the most popular disc made. Used in nearly every competitive Ultimate Frisbee game since 1983. The Ultra-Star was first manufactured in 1981 while the patent for the rings on a Frisbee flying disc was still in effect. So the intial Ultra-Stars had no rings. It wasn't until 1983 when the patent expirec did Discraft put rings on the disc.
