It looks like every world cup but perhaps a couple has had a different stitch pattern on the ball.
No, it doesn't. They were all somewhat different up until the Telstar introduced the 32-panel, pentagon-and-hexagon stitching pattern, but it appears to me that remained unchanged for almost 40 years, from 1970 to 2006. The balls in between appear to have the same stitching pattern, just different printed designs.
