Ohio Rev. Code Ann. § 5.49

The twelfth day of June is designated as "Superman Day" to recognize the Ohio birthplace of one of the creators of the superhero who stood for "truth, justice, and the American way." For on this day, let it be known that Superman is faster than a speeding bullet, more powerful than a locomotive, able to leap tall buildings in a single bound. Look! Up in the sky! It's a bird. It's a plane. It's Superman!
