Addendum (11/29 - 9:51 am): Please note that the Brooks Robinson signature on this card is a scarce vintage example dating from his early career and stands in stark contrast to the numerous later-day signing-show examples so prevalent in the hobby.
Dual-graded EX 5 - Auto 9 and encapsulated by PSA, this fine 1957 Topps #328 Brooks Robinson rookie card has been signed by the Hall of Famer himself in impressive blue "PSA 9" ink.
