Basketball Hall of Famer and six-time NBA MVP Kareem Abdul-Jabbar's auction for some of his personal memorabilia closed Sunday, per Goldin Auctions.

His title rings and memorabilia auctioned for almost $3 million.

Abdul-Jabbar explained why he was holding the auction in a Goldin Auctions blog post from September 2018:

"Much of the proceeds from my auction will go to support my charity, the Skyhook Foundation, whose mission is to 'give kids a shot that can't be blocked.' We do this by sending children from economically challenged schools to five days in the Angeles National Forest to experience the wonders of nature and learn the basics about science, technology, and engineering.

"Camp Skyhook is an immersive hands-on experience that takes kids out of school for five days and four nights. They go from auditory learning to utilizing all of their senses in the great outdoors. Our hope is not just to get them out of the city to commune with the outdoors, but to stimulate an interest in the sciences that might lead them to fulfilling careers."

Abdul-Jabbar is one of the world's most decorated and accomplished athletes. In addition to his six NBA MVP awards, the former Los Angeles Lakers and Milwaukee Bucks big man is a 19-time All-Star, a 10-time All-NBA First Team member and the NBA's all-time leader in points scored.

He averaged 24.6 points, 11.2 rebounds and 2.5 blocks per game for his career.

Abdul-Jabbar (then as Lew Alcindor) also dominated in the high school ranks. He led Power Memorial to three straight New York City Catholic titles and then enrolled at UCLA, where he won three national championships. He was named the national college player of the year and the Final Four's Most Outstanding Player during his three years with the varsity team.

Abdul-Jabbar's off-court accomplishments may be more notable, however. He earned the Presidential Medal of Freedom from President Barack Obama and has fought for social justice since his playing days as an amateur, notably boycotting the 1968 Olympics to protest racial inequality. He is also an accomplished writer and author.
