poster art, Catalog of Posters & Prints: Crystal Theatre, was published in 1982. Dolack married artist Mary Beth Percival on May 11, 1984. The same year, he began a series of works known as the "Invader series." The works feature animals "invading" human habitat, such as ducks swimming in a bathtub or a bear lying on the couch in a den in a house. The following year, Dolack—who was already "a nationally known poster artist"—produced the cover of the book, Wings to the Orient: Pan American Clipper Planes, 1935–1945: A Pictorial History. Dolack's father, Michael, died the same year. In 1989, Dolack's painting "Fast Forward" was featured in the show "Looking Forward" that exhibited emerging important artists, sponsored by the American Institute of Graphic Artists in Los Angeles. In 1990, Dolack donated a watercolor ("Restoring the Wolf to Yellowstone") depicting wolves looking over a plain of geysers and hot mud springs to the conservation group Defenders of Wildlife, with sales of the poster going to a fund to compensate local ranchers for the loss of livestock incurred due to the reintroduction of grey wolves into Yellowstone National Park. Although the fund also received donations from other foundations and proceeds from a benefit concert by rock artist James Taylor, the majority of the fund's proceeds came from sales of Dolack's art. The National Park Service in April 1990 banned the sale of the posters in Yellowstone and Glacier National Park. By 1993, his work had been shown in "hundreds of galleries, including some in Japan, Germany and France". That same year, he moved to a new, larger gallery at 139 W. Front Street. In 1998, Dolack donated his popular 1986 watercolor, "Blackfoot River," to the Blackfoot Legacy foundation for use as a fundraiser to oppose construction of a gold mine near Lincoln, Montana. The following year, the Idaho Rivers United foundation commissioned Dolack to create a new work (later titled "Resurrection") depicting a breached dam and the reintroduction of salmon and steelhead trout to the Snake River. The California clothing company Patagonia sold copies of the print through its stores and catalogs. The next year, Dolack's "Heron Blues" (a poster primarily in blue hues depicting a blue heron flying down a Montana city street at night) was included in the poetic collection Vagrant Grace. In 2000, Dolack painted a acrylic work, "A History Lesson," which depicted a full-grown American bison standing
