In the 1970s, personalities, ranging from the 1960's singing group Three Christy Minstrels, through William Kunstler, attorney for the Chicago Seven trial, Janis Joplin to Herb Caen, all would make their many visits to Mark Mulleian in the Frank Gallery.
		One late San Francisco evening William Ball, founder and president of the American Conservatory Theatre (ACT) entered the front door of the Frank Gallery. Draped in furs, accompanied by two affluent female members of his entourage, in jubilation he walked up to the artist and dropped to his knees in admiration and invited Mulleian's input for art direction and stage set design for a play being produced by The American Conservatory Theatre.
		On another occasion the mime, Robert Shields, entered the gallery and walked as a robot up to Mulleian. Then, suddenly Shields turned into a frog, leaping high into the air alongside the artist as they went for coffee.
		On a warm summer's eve, Janis Joplin suddenly appeared, standing motionless on the gallery floor, in rapt attention amidst Mulleian's paintings. Studying both paintings and artist, she eventually commented on the mysterious energies emanating from the material and expressed wonder at their technical expression while also expressing fear of Mulleian’s “heavy subject matter” when viewing one work in particular, his mysterious Stone Effigy. Ingratiated by her southern-comfort style of silk and ostrich feathers, lavender and magenta streaking through the air, chiffon trails floating behind her, she made her majestic way toward the front of the gallery. She left with a flourish and, looking neither right nor left, jaywalked her way through the rush hour traffic of Sutter Street.
		On another occasion, Mulleian would find himself holding and shaking the hand of Shirley Temple-Black in one of her many visits to the Frank Gallery. She admired Mulleian's work and expressed honor in meeting him. A few days later, she returned with her daughter.
		Many others would follow: Beverely Sills, Carlos Santana, Nate Thurmond, Elton Jhon, Herb Caen, Eric Hoffer, Beniamino Bufano, Ray Taliaferro, Tullah Hanley, Vicent Price, Thomas S. Szasz, David Garvey, Dirk Dirksen, Rev. Ray Broshears.
