Lavinia Lane received a check from Wilmore Enterprises, Inc., drawn on the Citizens Bank of Erehwon, in the sum of $10,000. Mrs. Lane indorsed the check "Mrs. Lavinia Lane for deposit only, Accounts of Lavinia Lane" and placed it in a "Bank by Mail" enveloped addressed to the First National Bank of Emanon, where she maintained a checking account. She then placed the envelope over a tier of mailboxes in her apartment building along with other letters to be picked up by the postman the next day. Flora Fain stole the check, went to the Bank of Omaha, where Mrs. Lane was unknown, represented herself as Lavinia Lane, and cashed the check. Has Bank of Omaha taken the check by negotiation? Why or why not?
