In this case are examples of mailers. Different political party representatives and parnters usually send out "mailers", cards with information of the candidate, to neighborhoods. People are either targeted by their documented interests in various candidates in past elections or when they give money to a candidate. These would also be considered campaigning tools, however, mailers are more of information rather than support.
This is an example of thoughtful and witty advertisement of candidates. As well, pill boxes, cups, beer labels, and magnets just some of the forms political parties use to get their name to the public.
