Description

A highly successful baseball bloodline is spotlighted, with the offering of this Ken Griffey Jr. and Ken Griffey Sr. dual-signed 1989 Costacos Brothers "The Next Generation" poster. Sized at 7" x 10", this vintage poster reports in crisp clean condition. The subjects have signed over their jerseys, and both signatures are bold applications. While Ken Sr. was nearing the end of his productive career, "Junior" was in his rookie season when this shot was taken. His prized autograph is identified as an early example, from a remarkable career that progressed all the way to the Hall of Fame.
