Looking impossibly young, Harmon Killebrew kicked off his major league career with the Senators in 1954 and, as a bonus baby, had to spend the season (and the next) on the major league roster. His scant rookie season output is noted by Topps on the reverse; he would blast the first of 573 career homers in 1955. Nicely rendered, the card is is bright, with just a touch of wear at the upper left seen, graded EX-MT 6 by PSA but exceptionally sharp and well-centered for the grade.
