Hello, I have the following scenario and I need to use IRAC to write a trial brief. Could you please help me with this?

My client, Susan Peterson, is suing Carl Fayette for breach of contract. Susan bought a baseball card on E-Bay from Carl. The item was a Mickey Mantle rookie card signed by the Hall of Famer, which included a letter of authenticity. Susan paid $4500 for the card. Susan was buying it for her 13-year-old son's birthday gift. When it arrived, Susan immediately noticed a problem. The card was signed, but the name was spelled incorrectly as "Micky Mantle." When Susan contacted Carl by email, he responded that "Mr. Mantle must have been intoxicated when he signed it." The letter of authenticity was also of concern. Carl was the person authenticating the item, and it was notarized at a Kinko's. Susan is now suing for the purchase amount and the costs of litigation.
