 An early supporter of Kennedy's run for the presidency, Marcus had tolerated the closing of several customers' accounts when he announced his support for the candidate in the 1960 elections.In fact, he had cautioned that Kennedy's visit be reconsidered in light of the city's earlier poor reception of Adlai Stevenson and Vice-President Lyndon Baines Johnson.In Kennedy's memory, Marcus arranged to have 500 hand-typeset and bound copies printed of Kennedy's scheduled speech at the Dallas Trade Mart, of which the first copy went to Kennedy's widow, Jacqueline.
