The first original full-sized painting of Superman was found hanging in a City University of New York library!
Check out the interesting mystery of how it got there at the New York Times here.
Thanks to my old high school English teacher, Mr. Kavanah, for the head's up!
Also, Marc Tyler Nobleman has an interesting blog post up on how various books about Superman chose to depict the Man of Steel on the covers of their books (without paying a licensing fee for the "real" Superman).
Check it out here.
And, quite nicely, Marc featured my book, Was Superman a Spy? and other Comic Book Legends Revealed (which you can always buy here) in the piece!
