In this middle period, Martin created some of his most absurdist work—for example, "National Gorilla Suit Day"—an extended narrative in which a hapless character is violently assaulted by a series of attackers in various disguises, including gorillas dressed as men. Charles Taylor described Martin's unique art style:  His people are big-nosed schmoes with sleepy eyes, puffs of wiry hair, and what appear to be life preservers under the waistline of their clothes. Their hands make delicate little mincing gestures and their strangely thin, elongated feet take a 90-degree turn at the toes as they step forward. Whether they’re average Joes or headhunters, Martin’s people share the same physique: a tottering tower of obloids. Martin puts the bodies of these characters through every kind of permutation, treating them as much like gadgets as the squirting flowers and joy buzzers that populate his gags: glass eyes pop out from a pat on the back; heads are steamrollered into manhole-cover shapes. All of this accompanied by a Dadaist panoply of sound effects found nowhere else: shtoink! shklorp! fwoba-dap! It’s unlikely Samuel Beckett was aware of Don Martin, but had he been he might have recognized a kindred spirit. His work probably reached its final peak of quality and technical detail in the late 1960s and early 1970s. In later years, particularly during the 1980s, he let other people write most of his gags, most notably Duck Edwing. Concurrent with his "Mad" output, Martin and an assortment of writers produced a series of paperback books, to which he retained the copyrights and eventual publishing rights. For this reason, the content of these books was not included in 2007's "Completely Mad Don Martin" box set. Martin described his heavy workload for these projects: Once I get the OK on the roughs I start the finished drawings. I sort of begin this stage slowly, because doing the finished work always ends up being a seven-day week. An all day, and all evening ordeal. I always anticipate I can draw the books faster than I can. That is a big mistake, since it adds a lot of anxiety, and aggravation to the project. I thought I had developed a system with the last one. I worked on the book in batches of 15 pages or so. I even kept a record to see how long it took me to do the pencils, and how long it took me to do the inks, but it still ended up being seven days a week for a couple of months.
