Venerable magazine Sports Illustrated will celebrate its 70th Anniversary next summer. While the print medium appears to be on the path to extinction, that should pump up the value of surviving back issues. No need to wait for coming value increases, as you can nab (6) SI issues that are already pumped up in worth by hosting prominent baseball and basketball star player autographs. Dating from the 1960s-1990s, these vintage 20th Century publications are generally solid, and the autographs are as stellar as those who provided them, averaging ("9-10") strength. Each autograph is individually certified with a JSA basic cert/sticker.
