In 1969 Bukowski accepted an offer from legendary Black Sparrow Press publisher John Martin and quit his post office job to dedicate himself to full-time writing. He was then 49 years old. As he explained in a letter at the time, "I have one of two choices – stay in the post office and go crazy ... or stay out here and play at writer and starve. I have decided to starve." Less than one month after leaving the postal service he finished his first novel, "Post Office". As a measure of respect for Martin's financial support and faith in a relatively unknown writer, Bukowski published almost all of his subsequent major works with Black Sparrow Press, which became a highly successful enterprise owing to Martin's business acumen and editorial skills. An avid supporter of small independent presses, Bukowski continued to submit poems and short stories to innumerable small publications throughout his career.
