Bidding for the billionaire's high-tech signed portrait will end on his 92nd birthday on Aug. 30

Billionaire Warren Buffett is making money for charity through the auction of a high-tech signed portrait of himself.

The bidding has already topped $30,000.

The auction started earlier this week and is open to bids until Buffett's 92nd birthday on Aug. 30.

The portrait of Buffett, created by Motiva Art, features a grid of letters over the picture that light up to spell out several of the legendary investor’s famous quotes.

The money raised will go to Girls Inc. of Omaha, which provides educational, cultural and recreational programs for young women in Buffett's hometown. 

The nonprofit has benefited from a number of other items the investor has auctioned off over the years.

Buffett once sold an old wallet of his that contained a stock tip, raising $210,000 for the organization. And in 2015, someone paid more than $122,000 for Buffett's 2006 Cadillac with his signature on the dashboard.
