Commemorative items from the life and career of Celtics patriarch Arnold "Red" Auerbach will be put up for auction starting in April, a California-based auction house announced in a press release.

The memorabilia includes Auerbach’s NBA championship rings from 1957, 1962, 1974, 1976, and 1981. Also available will be Auerbach's cigar humidor from the 1954-1955 season, a 1961 NBA All-Star golf bag, and a game-used jersey from 1950 won by Celtics rookie Bob Cousy that was part of Auerbach's personal collection.

The internet-based auction, conducted by SCP Auctions of California, will begin April 15 and run in three parts.

Auerbach had only one losing season in 16 seasons as coach of the Celtics. He won eight consecutive NBA championships before his retirement from coaching in 1966, then served as the Celtics team president and general manager for another 14 years. He was the team's president from 1984 until 1997 and again from 2001 until his death. Auerbach passed away from a heart attack in 2006 at the age of 89.
