This is a small series of superhero logos reimagined as neon signs by DeviantARTist 3ftdeep (which, for the record, is way too shallow to bury a body). They're not real. I don't see any reason why they couldn't be made real, but these are just renderings. My feelings for you? Those are real. "They are? Tell me how you feel!" I'd rather show you. "Wait, where'd you get the knife?"
Keep going for Batman and Superman.
Thanks to me, for being my own best friend and worst frienemy.
