Many, or most, of these cartoons have been published in periodicals and leaflets and web-sites, etc., around the USA, and some in Germany, the UK and Australia...and beyond.
Publications have included Z Magazine, Extra! (Fairness and Accuracy in Reporting), Public Citizen, Earth First! Journal, POCLAD, Food and Water, Solidarity, Synthesis-Regeneration, Compost Dispatch, Philadelphia Daily News, University City Review (Phila.), Green Left Weekly (Australia), Green Pages, Hawaii Island Journal, Funny Times, Wild Earth, Dollars and Sense, Dissent, Earth Island Journal, North Coast Xpress, Anderson Valley Advertiser, The Prism, The Partisan, Orion, Tox CAT (UK- Communities Against Toxics), Boycott Quarterly, Friends of the Earth, and others that I will add to this list when I remember them.
Cartoons have been, or still are, also used at web sites of various activist groups such as NORML, and various Single Payer health care advocates.
A bunch of cartoons were scattered throughout "Censored 2008" Project Censored's 2008 annual collection of top 25 Censored Stories, and in Teishan Latner's "The Quotable Rebel" ( http://www.commoncouragepress.com/index.cfm?action=book&bookid=356 ), an invaluable book of quotes that are especially usable by political activists.
Other work is periodically used in commercial textbooks.
A lot of the cartoons have been graciously hosted at Paul Goettlich's amazing Mindfully site...which he no longer administers, but is still there. http://www.mindfully.org
My cartoons (not all) are at http://www.mindfully.org/Jonik/index.html

Cartoons are free to use for non-commercial purposes, but if a user has established policies for payment for graphics, I would, of course, accept that. If it is convenient, I'd appreciate a copy of the issue in which a cartoon appears. And I ask that any reprint requests be forwarded to me.
For commercial uses, whatever the established rates are will suffice...and, again, I ask for a copy of the issue in which a cartoon appears....and that reprint requests be sent my way.
If higher resolution copies are needed, I will be glad to accommodate.
If categories like Drug War, Environment, Health Care, General Cartoons are not up on the opening pages, they can be found at clicks of different dates on the upper right side of the opening page. Don't know why this is made so difficult. Sorry for any inconvenience.
