Starting Thursday and lasting for one week only, DVD Express, will be hosting an online celebrity and movie memorabilia auction to benefit Cedars-Sinai’s C.O.A.C.H. for Kids Mobile Medical Clinic.

Among the more than two dozen items up for bid are a signed guitar from The Eagles; a personal item from Barbra Streisand; autographed boxing gloves from “Sugar Ray” Leonard, Oscar de la Hoya and Evander Holyfield; Sylvester Stallone’s hiking boots; a Cheryl Tiegs collection including jewelry, a bathing suit, signed 8×10 photo and signed magazine; a signed script and 8×10 photo from “Dharma & Greg”; a Magic Johnson autographed basketball; a Kenny G autographed CD; and more.

Every item featured in the celebrity auction comes with a certificate of authenticity directly from the donor or from a representative of the celebrity’s estate. The auction will end on Wednesday, June 2, at 6 p.m. PST.

All proceeds will benefit the Cedars-Sinai C.O.A.C.H. for Kids Mobile Medical Clinic, a fully equipped state-of-the-art “clinic on wheels,” which provides free medical and preventative services to economically fragile children in underserved areas of Los Angeles County.
