When I was considering buying this piece from its original purchaser, I asked Trina Robbins, by far the best of the original female underground comix crowd and the premiere women's comic art historian, about it and she was kind enough to give me a complete history, some of which follows. This was a big factor in my deciding to get it
"This was a piece I originally did it to submit to Heavy Metal, but they weren't interested (not sexy enough, I suspect), so I sold it instead to the publisher of Deadspawn... Deadspawn was a very creatively put together bit of self-publishing, but unfortunately hardly anyone has ever seen it. The story was inspired by a visit to Hawk Tower, built by my favorite American poet, Robinson Jeffers, on the coast of Carmel, California. In the story, a woman soldier, one of the last survivors of a nuclear holocaust, and dying of radiation poisoning (though she doesn't know it), wanders down the coast and comes upon the tower, where she also meets all the fairies, who have come out of hiding now that mankind is dying. They force her to join them in a kind of dance of death, she dies, and Titania, the fairy queen, announces that now that the last human is dead, the world is safe for the fairies again. Bit of a downer, I know..."
Trina was kind enough to send me a copy of the story. Dead spawn was a collection of comic broadsheets packaged together. It is smaller than regular comic book sides and is printed on two sides of a long, multiply-folded sheet.
This is an amazing piece of airbrush art. What you see is what Trina created with no cgi whatsoever. I think Titania is gorgeous, too bad about the humans though.
