A jacket sporting the Reebok logo and reluctantly worn by Michael Jordan during the 1992 Barcelona Olympics is heading to auction.

The jacket, which will be auctioned by Sotheby’s, according to NBC Sports, originated from Brian McIntyre, an employee of the NBA’s communications department who went on to later work as an advisor to former commissioner David Stern.

McIntyre was in attendance at the ’92 Olympics medal ceremony, and Jordan gifted him the jacket after exiting the metal stand shortly after winning gold.

Jordan, who signed with Nike in 1984, wasn’t amused with the idea of promoting the competition but had been required to wear the team clothing for the ceremony. So, the hand off was proof of his loyalty to Nike.

“He said, ‘I certainly don’t want it,’” McIntyre recalled, according to the outlet.

Jordan also signed the valuable piece at a later time, writing “To Brian, Thanks for Everything, Michael Jordan.”

McIntyre has been in possession of the jacket for nearly 30 years, and he understands its significance. Outside of it being worn by Jordan, it also represents a prominent era in basketball history.

For the first time ever, active professional athletes joined the U.S. team at the Olympics.

In addition to Jordan, the “Dream Team” also included Magic Johnson, Larry Bird, Charles Barkley, Karl Malone, John Stockton, Patrick Ewing, David Robinson, Clyde Drexler, Scottie Pippen, Chris Mullin, and Christian Laettner.

“We watched the ‘Dream Team’ in the ’92 Olympics fast-forward the growth of basketball, by a lot,” McIntyre reflected, according to NBC Sports. “I mean, it really helped develop the game worldwide — not just for the NBA, but in basketball in general.”

Due to Jordan’s legacy and the league’s development since those Olympic Games, it’s no surprise the jacket is expected to sell for a significant amount.

According to the outlet, the projections are between $1 million and $3 million with the auction running through June 28.

“To be able to sell this relic from such a historic world event — one that is often credited for multiplying the popularity and global reach of basketball — is both rare and unparalleled,” said Brahm Wachter, Sotheby’s head of streetwear and modern collectibles, in a report from NBC Sports. “And beyond its legendary place in Olympic history, the jacket represents Michael Jordan’s fierce and devoted loyalty to Nike, a transformative and revolutionary partnership between two powerhouses that has stood the test of time.”
