Dallas-based Heritage Auction Galleries has filed a lawsuit against two dealers of Hollywood memorabilia, claiming items it sold for the pair were bogus.

Filed Wednesday in Dallas County district court, the lawsuit alleges that John A. Tarter and Billie Hugh Null, partners in L.A. Prop and Wardrobe Co., misrepresented the authenticity of a whiskey flask, engraved cigarette case and 20 objects auctioned last year as the Ann Sothern Collection.

Heritage has offered refunds, including interest, to the 11 people it says paid $35,000 for the 22 items last April.

The lawsuit accuses the men and their company of fraud, negligent misrepresentation and breach of contract. It seeks to recover the company’s financial loss, as well as unspecified punitive damages.

Mr. Tarter, a resident of Nampa, Idaho, said Thursday that the items are legitimate and were purchased in 2002 from a collector named Ron Martin in Los Angeles. He said he has been trying to contact Mr. Martin but has neither his address nor telephone number.

Before the sale, L.A. Prop gave Heritage letters of authenticity for each of the 22 items.
