I'm not sure how accurate the dating is, but April 18 is a day given over to the character of Superman, and this the 75th year of his first publication. That's a really great character, and a remarkable achievement by his creators, Jerry Siegel and Joe Shuster. I hope that you'll remember Siegel and Shuster today as much as you remember the character. I think there's a reason that we see language about the latter as much if not way more than the former. I like imaginary characters, and Superman is about as broadly appealing as they come, but I like artists and writers more and I think theirs is the accomplishment worth celebrating.
