TUSTIN, CA - Bidding in the Memory Lane Inc. auction ends tonight at 10 p.m. EST, Thursday, May 5.

The auction is jammed with rare sports cards and memorabilia from virtually every era of professional sports including a 1921-31 era game-used Babe Ruth bat. Minimum bid is $7500.

Beyond the Ruth model, the auction includes a wide selection of game-used bats from virtually every era and a cavalcade of stars like Cobb, DiMaggio and Maris.

Also offered is a baseball signed by both Ruth and Lou Gehrig, a relic from their barnstorming days of the 20's. The ball is dated October 27, when the "Bustin' Babes" and Larrupin' Lous were in Santa Barbara, California. The dual-signed ball carries a $7500 starting bid.

Two original Yankees World Series rings are offered: a 1999 ring given to Jose Cardenal, then a coach with the Bronx Bombers; and a 2000 model presented to coach Carlos Rios.

The Spring Fever auction includes a huge group of autographed Michael Jordan items. Offered are signed basketballs, jerseys, photos, shoes, cards, a cancelled check and even several baseball-related Jordan pieces, highlighted by a signed bat and an autographed White Sox jersey.

Five pairs of 2008 Eastern Conference Finals-worn LeBron James Nike shoes are up for grabs, all signed and authenticated by Upper Deck Authenticated.

Memory Lane's usual bounty of rare, vintage sports cardboard is topped by multiple original Babe Ruth cards, including a 1933 Goudey #144 graded NM/MT and a 1952 Topps Mickey Mantle graded PSA 5, the latter already generating strong bidder interest.

There is also a 1948 Leaf Jackie ("Jacky") Jensen red back error (PSA 8.5), one of several high-grade '48 Leaf football being offered.
