Add the compact action image of the most consequential run in Seattle Mariners history to your collection with this Ken Griffey Jr. Autographed Seattle Mariners 8x10 Photo "The Slide" — BAS Witnessed. Two photographs document October 8, 1995. One captures the celebration — Griffey at the bottom of the dogpile, the grin of relief and joy after the series-winning run scored. The other captures the run itself: Griffey in full sprint, body extended toward home plate, dirt rising, the throw arriving, the outcome still undecided. The Slide is the action image. The Dogpile is the reaction image. Both exist in the 8x10 format — both signed by Griffey, both authenticated by a Beckett representative who was physically present at the signing — and both document the same four-second span from opposite ends: the moment of execution and the moment of confirmation. For the collector who wants to own October 8, 1995 at desk scale in its most complete available form, the 8x10 Slide is the action half of that pair.
This Seattle Mariners 8x10 Photo "The Slide" has been hand-signed by Ken Griffey Jr. with a bold, clean autograph. Authentication is provided by Beckett Authentication Services (BAS) at their elevated Witness tier — a Beckett representative was physically present at the signing to verify the autograph's authenticity in real time.

Kinetic at Compact Scale — What the 8x10 Slide Offers
An action photograph at 8x10 scale delivers something a reaction photograph at 8x10 scale does not: energy compressed into a small frame. The Dogpile photograph, at 8x10, brings warmth and joy to desk scale — the grin, the pile, the relief. The Slide photograph, at 8x10, brings motion to desk scale — the sprint, the dirt, the extended body, the throw arriving, the fraction of a second before resolution. These are not the same viewing experience at any format, and they are especially distinct at the compact scale where the photograph and the viewer are closest to each other. The Slide at 8x10 puts the most athletic image of Griffey's Seattle career in the tightest available display relationship with the collector — the image most concentrated with physical energy, at the format most concentrated with the autograph. Griffey's signature on the 8x10 Slide occupies a larger proportional presence relative to the action in the frame than the same signature on a 16x20 — the autograph and the sprint exist in the most intimate available scale for this specific photograph. For a collector who has the 8x10 Dogpile and wants its complement in the same format, the 8x10 Slide completes the pair: the action half and the reaction half of the same October night, both at desk scale, both BAS Witnessed.
The Son's Game — A Father's Inheritance
Ken Griffey Jr. grew up in baseball clubhouses. His father, Ken Griffey Sr., played for the Cincinnati Reds from 1973 to 1981 — the Big Red Machine era, back-to-back World Series championships in 1975 and 1976 — and young Junior was a regular presence in the Reds' locker room, absorbing the game from the inside of a championship organization before he was ten years old. When Senior joined the Seattle Mariners in 1990, father and son briefly shared a roster — the first time a father and son had played together in major league history. On September 14, 1990, they homered in the same game against the California Angels — the only father-son pair in MLB history to hit home runs in the same game. Junior was 20 years old. Five years later, with his father watching the 1995 ALDS from outside the playing field, Junior scored the run that gave Seattle its first playoff series victory in franchise history — the run that The Slide photograph captures in the instant of its execution, before the umpire's hand went up and the Kingdome erupted. The photograph is a baseball moment. But it is also the end of a story that began in a Reds clubhouse in the 1970s: a son who absorbed the game from his father and delivered the most consequential individual moment in the history of the franchise that made him famous. The 8x10 Slide signed by Griffey carries that full arc in the autograph at the bottom of the image.
The Face of Baseball in His Most Athletic Image
By October 1995, Ken Griffey Jr. had already appeared on the cover of Sports Illustrated, tied the MLB record for home runs in consecutive games (eight, in 1993), and been called the new face of baseball by every major outlet covering the sport. He wore his cap backwards. He played center field with a looseness and joy that made his defensive highlights as watchable as his offensive ones. Nike had built a signature line around him. A Nintendo video game bore his name — the only active major league player with that distinction in that era. When the camera captured The Slide on October 8, 1995, it captured the most famous baseball player in the sport in the most physically committed athletic action of his career to that point — not a swing, not a catch, but a full-speed sprint toward a plate with a throw coming in and a series on the line. The Slide is the most kinetic image in the Griffey catalog: the player who was defined by the effortless swing and the acrobatic catch, photographed in the moment of maximum physical effort and maximum competitive stakes. The 8x10 format brings that specific image — the face of baseball in his most urgent available moment — to the compact scale where the collector and the image are as close as the signed photo format allows.
