2016’s contentious political campaigns and the candidates’ saturation TV ads will soon be history, but collectors will see to it that the memorabilia left behind lives to see another day. Presidential campaign mementos – the signs, banners, buttons, hats and other ephemera produced to publicize candidates and fire up voters – rank among the few things besides rocks and bottles that collectors can pick up for free. In fact, there are diehard collectors who, like Deadheads, go from city to city following campaigners and collecting free memorabilia printed or manufactured specifically for a particular region.
