Harmon Killebrew hit 573 career home runs eighth on the all-time list as he topped the 40 plateau in eight seasons and captured six American League homer titles. A right-handed hitter with a big swing the balding round-faced "Killer" did not hit many line-drive home runs-most of his were towering fly balls that soared into the stands anywhere from the right-center field gap to the left field line. They usually were prodigious and memorable. So were Killebrew's run-production numbers over 22 seasons 21 of which were spent with a Minnesota Twins franchise that shifted from Washington in 1961. Batting cleanup in a 1960s lineup that included Cesar Tovar Tony Oliva Rod Carew and Bob Allison Killebrew provided the hammer for offensive-minded Twins teams that lost in the 1965 World Series to Los Angeles and claimed West Division titles in 1969 and '70. Presented here is the single finest example of Harmon Killebrew's 1955 Topps rookie card according the PSA census. Its exemplary features include a background hue of blazing yellow that deploys the youthful likeness of the Senators' slugger in more subtle yet equally impressive tones. Immaculate surfaces razor edges and perfect centering more than justify this cards status as the only GEM MINT 10 example among 2716 Killebrew rookies that have been subjected to the scrutiny of PSA to date.
