Back when he was still working on the strip I was a little boy, and I thought Moon Maid looked strange. But what I really dislike now was what somebody who didn't have anything to do with the original comic strip did to the character later on.
I was told that Chester Gould no longer read the comic strip after he was taken off of it. This was just as well, as one of the things Max Allan Collins did was to kill Moon Maid off.
I am not a fan of Max Allan Collins. Even apart from the Moon Maid business, I didn't like anything he did. And I can't say I'm a fan of the current writer on the strip, either.
Moon Maid is Moon Maid, pure and simple. "Mysta" was the name of another character that they used to have in Planet Comics.
