TULSA, Okla. (AP) — The 100,000 or so artifacts earmarked for the would-be Oklahoma Museum of Popular Culture have for several years been neatly tucked away in numerous boxes at the state's history center in Oklahoma City. While historians pined for the day when they'd be able to show off all the films, recordings, art and other memorabilia, critics assailed the proposal as a vanity project that would never get off the ground. Now, the OKPOP museum in Tulsa has a heartbeat.
