A professor of John Steinbeck once told him that he would only be a writer “when pigs fly.” Steinbeck, of course, later became a Pulitzer Prize and Nobel Prize-winning writer. 

Ad astra per alas porci (“to the stars on the wings of a pig”) is the Latin motto he used along with the Pigasus image to symbolize himself  –“earthbound but aspiring.“ The pig has indeed flown.
