Mickey Klar Marks left her mark on comics, literally. First, She wrote a lot of text pages which are credited to her. Second, she left her record books to the University of Mississippi, so we know what comic stories she wrote as well, Well sorta, as she didn't list where these stories appeared, but rather when she was paid.
And yes. she was paid for work for Timely. As one can see from the short list below, she didn't write much for Timely, 1 text story in 1946, 9 humor stories in 1948, and 2 text stories in 1949.
