Well, this just breaks my heart.
Here we have this clearly awesome young lady writing to DC Comics in 1959 with some adventure ideas for her hero, Lois Lane. She suggests some fun careers (since, y'know, anything goes in the wacky Silver Age).
Then we get this very depressing response:
Reach for the stars, little Ethel!
The worst part is that I'm pretty sure the writers did end up stealing all of Ethel's ideas in later issues.
