If you’re all about pop-culture collectibles, visiting Mondo Gallery is a must for your ATX museum agenda. Located just north of University of Texas campus, Mondo creates and displays limited-edition screen-printed posters for handpicked classic and contemporary films, TV shows and comics, its own versions of vinyl movie soundtracks (oh, you don’t have that clear, 180-gram Back to the Future II score?), VHS re-issues, plus various toys and apparel. Better yet, most of these items, often part of temporary exhibits that run a few weeks at a time, are for sale. Can’t make up your mind about a purchase on the spot? No worries—their website stocks most of these treasures (while supplies last).
