This cartoon is the original version of the Make Guano – Not War strip (the strip was published on this website in 2010, you can see it here). It was also the base for the cover of the first POLE Collection (Which is available in B/W or in full color here).
BTW, the second POLE Collection: Is It Climate Change Yet? will be available soon, as soon as I will find some time to finish up the printing files!!
