Grace Barnett Wing was born October 30, 1939, in the Chicago suburb of Highland Park, Illinois, to Ivan W. Wing (1907-1987), of Norwegian and Swedish descent, and Virginia (nee Barnett; 1910-1984), a lineal descendant of passengers of the Mayflower. Her parents met while they were both students at the University of Washington, and later married. In 1949, her brother Chris was born. Her father, working in the investment banking sector for Weeden and Company, was transferred several times when she was a child, and in addition to Chicagoland, she lived in Los Angeles and San Francisco, before her family finally settled in the San Francisco suburb of Palo Alto, California in the early 1950s.

After retiring, and after a house fire, divorce, and breakup, Slick began drawing and painting animals, mainly to amuse herself and because doing so made her happy during a difficult period in her life. Soon thereafter, she was approached about writing her memoir, which ultimately became Somebody to Love? A Rock-and-Roll Memoir. Her agent saw her artwork and asked her to do some portraits of some of her various contemporaries from the rock-and-roll genre to be included in the autobiography. Hesitant at first (because she thought "it was way too cute. Rock-n-Roll draws Rock-n-Roll"), she eventually agreed because she found she enjoyed it, and color renditions of Janis Joplin, Jimi Hendrix, and Jerry Garcia appeared in the completed autobiography. An "Alice in Wonderland"-themed painting and various other sketches are scattered throughout the book. Her paintings of Jorma Kaukonen and Jack Casady were used for the cover art of the album The Best of Hot Tuna. Though Slick has been drawing and painting since she was a child, she admits to not being able to multitask, so did not do much of it while she was focusing on her musical career. A notable exception is the cover art of her first solo album, Manhole, which she signed "Child Type Odd Art by Grace."  Slick is not bound by any specific style or medium in her production of visual art and has no interest in developing one. She uses acrylic paints, saying oil takes too long to dry, canvas, pen, ink, scratchboard, pastels, and pencil. Many of her works are mixed media. Her styles range from the children's bookish "Alice in Wonderland" themes to the realism of the rock and roll portraits and scratchboards of animals to the minimalist ink wash styled nudes to a variety of other subjects and styles.  The best-selling prints and originals are her various renditions of the white rabbit and the portraits of her colleagues in the music industry. In 2006, the popularity of her "Alice in Wonderland" works led to a partnership with Dark Horse Comics, Inc. that resulted in the release of stationery and journals with the "Wonderland" motif.  While critics have variously panned and praised her work, Slick seems indifferent to the criticism. She views her visual artistry as just another extension of the artistic temperament that landed her in the music scene in the first place, as it allows her to continue to produce art in a way that does not require the physical demands of appearing on a stage nightly or traveling with a large group of people.  Slick attends many of her art gallery shows across the United States, sometimes attending over 30 shows in a year. While she says she enjoys talking with the people who come to her art shows, she is not a fan of the traveling involved, particularly the flying. At most of her art shows, those who purchase a piece of her art get a photo with Slick, an opportunity to chat, and a personalized autograph on the back of the piece that has been purchased.
