During the 1970s Mulleians works had not gone unnoticed by leading art critics and San Francisco's art academies.

Although Mulleian’s vast subject matter is considerable and far reaching, unlike any other artist before, it is not without its controversy which would find its way rumbling through the halls and conference rooms at San Francisco Art Academy and the Department of Art at San Francisco State. During the early 1970’s the Academy of Arts committee in San Francisco debated over Mulleian’s paintings in a board meeting focusing on the artist’s subject matter, splitting the committee in half. Their criticism was over Mulleian’s wide range of subject matter. As if to say “One who paints seascapes should only paint seascapes. One who paints portraits should only paint portraits.” Half of the committee members disagreed. In reaction to the Academy’s criticism, Mulleian responds, “I have nothing more to say except, I have more to say.” Mulleian's name would also reach the lips of art critic Alfred Frankenstein, professor of Art History, were he engages in a discussion of Mulleian’s art in his classroom at the University of California at Berkeley. At the time the artist stated: His greatest horror is for any artist to diminish their work by allowing the popular or conventional influences of the establishment to overshadow the integrity of the creative vision. To capitulate is to lose ones voice.

Art Critic Thomas Albright

I In 1972, the late Thomas Albright, northern California's influential art critic for the San Francisco Chronicle published a weekend edition on Mulleian's new surrealism, accusing the artist of attempting to turn back the clock to the literalism of a bygone era, such as that of the Dutch and Italian Renaissance masters. Albright found this to be a threat to the sensibilities of the 1970’s loosely defined art world of abstract expressionism, conceptualism and experimental modernism. Mulleian responded: "Should I take Albright's comments literally or conceptually?" A day later the San Francisco Examiner ran to Mulleian's defense. Art critic William Zakariasen wrote, "An impressive exhibit of large scale paintings is at the Frank Gallery by Mark Mulleian that has a worthy message with well developed technique to translate it to the viewers. Mulleian's fine sense of perspective and anatomy of heroic figures is reminiscent of Caravaggio."

Explosive Debate: Herb Caen vs. Thomas Albright

In his ‘Baghdad By The Bay’ column, the Chronicle’s iconic Herb Caen frequently lauded Mulleian’s work all through the 1970s, but in 1972 an explosive dispute developed that quaked through the entire San Francisco Chronicle building, even reaching the streets and the people “in the know”. The dispute had to do with Thomas Albright’s apparent belief that anything having to do with the subject of art should come only from Mr. Albright, an opinion that abruptly engaged Caen’s critical attention. Caen disagreed. With his characteristic cosmopolitan tact he made it clear that when it came to the story on Mulleian it didn't just fall into Mr. Albright’s jurisdiction. He rightly argued that any story expounding the talents of Mulleian or the nature of his work would have to do not only with art but also with the young artist’s contribution to the broader cultural story of the moment by an original San Francisco personality. When the dust settled, Caen’s position prevailed.

Tullah Hanley, world renowned art connoisseur

In one of her visits to San Francisco in 1980, world renowned connoisseur of the arts Tullah Hanley, after viewing a feature exhibit of Mulleian’s paintings at the Visual Experience Gallery, compared Mulleian’s technique to that of the post-Renaissance Dutch and Italian Masters in composition, detail and his palette of tonal tour de force. Hanley, whose major collection of paintings would eventually be bequeathed to the De Young Museum, descending from the upper gallery in a burst of spontaneous enthusiasm, grasped the artist’s hand, voicing impassioned admiration and praising his work as the best she had ever seen in a long time.

In 1973 Mulleian comes out

In January 1973, The Advocate (a national newspaper in the U.S.) published one of the biggest feature stories on an individual of its day, which drew national attention and generated fan mail throughout the U.S. The cover story was two full pages dedicated to Mark Mulleian's art and lifestyle, and his views ranging from human rights and individual sexual expression. It was in the area of individual sexual expression that Mulleian's outspoken views drew the attention of the FBI to the front door of the artist's studio in an investigation into his controversial and challenging commentary of aspects of fundamental social values, Mulleian reveals that he is a homosexual.

Despite the artist's outspoken observations of the national scene, his media attention continued to climb for over three decades, not only in mainstream media but also in the media of a newly emerging counterculture that was finding its voice in what would later come to be thought of as a bridge between the sensibilities of North Beach and the dawning of a new age of personal expression and sexual freedom. He was thought by many to be ahead of his time. Mulleian's art and his avant-garde views created a unique relationship with the media of two cultures, a relationship that was not only unprecedented but, indirectly, a testimony to the universality of his work.

Two weeks after the Advocate story broke, a similar two-page cover feature would appear in the European equivalent of the Advocate, the German magazine Him, a monthly periodical reaching a wide audience in Belgium, Denmark, England, Italy, the Netherlands, Austria, Switzerland, Luxembourg and the United States. Mulleian was twenty-three years old.
