Textbook Brokers/Blue Raider Book and Supply used to be a fast food restaurant originally. Burger Queen with the "Queenie Bee" as their mascot. It was a regional chain of burger restaurants (think it was headquartered in Louisville). Manchester had one as did Cookeville near Tenn. Tech. They became Druthers in the early eighties, but by then Murfreesboro's closed (around 1979, IIRC). Mom used to stop there after school and get a me burger in the 1970's. There were 2-3 other restaurants that I can't recall off hand before Blue Raider moved there (think they came in around 1986-87).
The original Blue Raider Bookstore was at 114 Baird Lane at College Heights (next to what's now Domino's Pizza). That was a cool fascinating two-level store! Closed around 1982. The original Blue Raider Bookstore carried hi-fi equipment upstairs (Marantz, Superscope, JBL and Sony) and had cool movie posters of its day displayed on the walls (Jaws, original Star Wars, Close Encounters, Smoky and the Bandit, Kramer vs Kramer, 9 to 5 are a few I distinctly remember). They also carried hi-end art supplies, fraternity/sorority shop, the requisite textbooks and school supplies, along with a mini-market setup near the front. Baird Lane building was razed in the 1990's after Jabb's International Cuisine closed (Jabb's was there when I was an MTSU student).
