Apparently the block with question mark doesn’t have 1UP or super mushroom, but if you want to illuminate your room, the Super Mario styled pendant lamp will help you.
This is a pretty cool pendant lamp themed by Super Mario Bro video game series, and handmade by Pete Betcher from Austin. The pendant lamp measures 16.5 x 5.5 x 5.5 inches, and as we can see from the images, the lamp is shaped as three iconic blocks including a question mark block from the universe of Mushroom Kingdom, but don’t break the blocks, you can’t get any coin or special mushrooms, however, using included bulb the pendant lamp illuminates your room. Moreover, the Super Mario styled lamp is made of a quarter inch polar frame, colored translucent acrylic and paper. Apart from that, its two openings make it double as a wall lamp.
