The fonds consists of original Windsor Star editorial cartoons drawn by Mike Graston that reflect local, provincial, national, and international public affairs of the period 1981-2016. The images have been arranged by date of creation. Politics and politicians figure prominently, at all four levels.

Municipal topics include mayors and city councillors, elections, public utilities and infrastructure, local Canada-US border crossings, automakers and other major local employers, unions and strikes, strip clubs, casinos, the downtown core, and riverfront development plans.

Provincial topics include premiers and Windsor/Essex members of provincial parliament, party leaders, economic policies, education, health care, and elections.

National topics include prime ministers and Windsor/Essex members of parliament, party leaders, economic policies, taxation, national defence, elections, same-sex marriage, Quebec separatism, Western alienation, and many political scandals.

International issues include wars in Iraq, war in Afghanistan, school shootings, the British Royal Family, American presidential politics, and Canadian-American relations.

Social issues are a secondary focus, with recurring themes of technological change, demographic change in Canada, Western popular culture (including television, sports, music, and celebrities), Remembrance Day, public health, and the environment.

A small amount of biographical information about Mike Graston and past exhibits of his work is also included in a textual file.
