The first 5 images in this post are covers from books by Manic D Press:
Manic D Press was founded by Jennifer Joseph in 1984. An award-winning literary press based in San Francisco, California publishing fiction, poetry, pop culture, music, art, narrative-oriented comix, and alternative travel books, we represent a diverse group of unique writers and artists, with emphasis on those who have been shunned by the traditional publishing establishment for lacking commercial viability, regardless of their talent or future promise.
The last 4 images are from Last Gasp:
Last Gasp is one of the largest and oldest publishers and purveyors of underground books and comics in the world, celebrating its 41st year in business. Over the years we have published, and in some cases brought to light, some of the most respected and talented artists working today, including R. Crumb, Justin Green, Bill Griffith, Mark Ryden, Aline Kominsky-Crumb, Frank Kozik, Todd Schorr, Winston Smith, Spain, Robert Williams, and countless others. Today, we publish 12-20 new titles per year, focusing on ‘lowbrow’ and ‘pop surrealist’ artists, as well as graphic novels and pop culture titles. We also distribute all sorts of weird ‘n’ wonderful subversive literature, graphic novels, tattoo, and art books, supplying them to bookstores and art galleries on six continents.
