Amazon Bookstore, Minneapolis
I did some online research and found out about the interesting herstory of the 'Amazon Bookstore', including this great video, this Wikipedia article, and this newspaper article.
This bookstore and art gallery opened in 1976 and closed in 1983, due to financial issues.
Sister Moon Feminist Bookstore & Art Gallery in 1977 had one store, at 1625 E. Irving, later advertising (approx. 1978) listed a second location at 2128 E. Locust in Milwaukee. At that time, their ad indicated that, "Besides 2,000 book titles, we carry: pottery, weavings, glassblowing, leather, stained glass, batiking, record albums, t-shirts, posters, prints, and photography".
This bookmark (front & back) is c. 1980.
