a wave of over two dozen co-ops affiliating with the IWW under its Wobbly Shop model in the 1960s to 1980s. These businesses were primarily in printing, publishing, and food distribution; from underground newspapers and radical print shops to community co-op grocery stores. Some of the printing and publishing industry co-ops and job shops included Black & Red (Detroit), Glad Day Press (New York), RPM Press (Michigan), New Media Graphics (Ohio), Babylon Print (Wisconsin), Hill Press (Illinois), Lakeside (Madison, Wisconsin), Harbinger (Columbia, South Carolina), Eastown Printing in Grand Rapids, Michigan (where the IWW negotiated a contract in 1978), and (Montreal). This close affiliation with radical publishers and printing houses sometimes led to legal difficulties for the union, such as when was shut down in 1970 by provincial police for publishing pro-FLQ materials, which were banned at the time under an official censorship law. Also in 1970, the San Diego, California, "street journal" became an official IWW shop. In 1971 its office was attacked by an organization calling itself the Minutemen, and IWW member Ricardo Gonzalves was indicted for criminal syndicalism along with two members of the Brown Berets. These ties to anti-authoritarian and radical artistic and literary currents would link the IWW even more heavily to the 1960s counterculture, exemplified by the publication in Chicago in the 1960s of Rebel Worker by the surrealists Franklin and Penelope Rosemont. One edition was published in London with Charles Radcliffe, who went on to become involved with the Situationist International. By the 1980s, the Rebel Worker was being published as an official organ again, from the IWW's headquarters in Chicago, and the New York area was publishing a newsletter as well. Return to workplace campaigns Invigorated by the arrival of enthusiastic new members, the IWW began a wave of organizing drives. These largely took a regional form and they, as well as the union's overall membership, concentrated in Portland, Chicago, Ann Arbor, and throughout the state of California, which when combined accounted for over half of union drives from 1970 to 1979. In Portland, Oregon, the IWW led campaigns at Winter Products (a brass plating plant) in 1972, at a local Winchell's Donuts (where a strike was waged and lost), at the Albina Day Care (where key union demands were won, including the firing of the director of the day care), of healthcare workers at West Side School and the Portland Medical Center,
