The 1973 Topps #607 Ray Busse Rookie Card is a great vintage collectible featuring three rising shortstops of the era: Pepe Frías (Expos), Ray Busse (Cardinals), and Mario Guerrero (Red Sox). As part of the classic 1973 Topps "Rookie Shortstops" subset, this card captures a moment in baseball history when these players were making their mark in the league. 

Graded PSA 6 (EX-MT) for its overall condition, the true highlight is Ray Busse’s autograph, authenticated by PSA/DNA and awarded a perfect Auto Grade 10, ensuring a pristine and verified signature. This multi-player rookie card is a unique addition for collectors of 1970s baseball memorabilia and those who appreciate authenticated signatures on classic Topps designs.
