1977 Topps Baseball #437 - Turn Back The Clock Ralph Kiner

• Leading the league in anything for seven straight years is quite an accomplishment. 
• The closest streaks I could find were:
• Walter Johnson - AL strikeout leader for 8 straight years (1912-1919)
• Dazzy Vance - NL strikeout leader for 7 straight seasons (1922-1928)
• Lefty Grove - AL strikeout leader for 7 straight years (1925-1931)
• Rogers Hornsby - NL Batting Average leader for 6 years in a row (1920-1925)
• Ty Cobb led the AL in batting average every year from 1907-1919 except for 1910 (Nap Lajoie led) and 1916 (Tris Speaker was the BA champion). 
• Sandy Koufax - NL ERA leader for 5 straight years (1962-1966)
