In the late 1960s the blacklight poster industry took off in studios all over the country, but was primarily centered on the West Coast. Poster artists experimented by using printing inks that fluoresced under blacklight bulbs that emitted ultraviolet light, making posters that appeared to glow and magically radiate their own light.  Turned On!: American Blacklight Posters, 1967-71 offers viewers an opportunity to experience the fun of stepping into a 60s style blacklight room featuring 10 posters and an Op art dress.  This unique show was organized by artist Gary Westford and drawn from his personal collection.  Hours: 10am-5pm  Tues-Sat;  1-5pm. Sun. Closed Mon. Cost: $6 general; $4 seniors (age 55+); $3 college students (age 18+ with ID); free for children (ages 0-17). Tuesday: Free.  Hallie Ford Museum of Art 700 State St.
