The "boom" isn't over in baseball memorabilia.

And at 5 p.m. Saturday, Dec. 8, at Cottonwood High School, perhaps the biggest gun in the game will be putting in an autograph appearance.Ken Griffey Jr. - dubbed "The Natural" by Sports Illustrated - will be in town for the Sports Card Extravaganza Sports Show. The Seattle outfielder had a banner year in 1990, capturing the hearts of fans along with several other awards.

Admission to the show (which will also have 110 dealers hawking their wares) is $3. A Ken Jr. autograph will cost $10.

Be ready to hurry up and wait. There's bound to be a crowd.

Ken Griffey Sr. and Hal Morris will also be on hand earlier in the day to sign autographs and chat with fans.

The doors at Cottonwood High, 5717 S. 1300 East, will open at 10 a.m. and close at 9 p.m. For more information call 250-9798 or 825-4158. - Jerry Johnston
