Searching for Mike Quin

This is in reference to an article I wrote about the San Francisco Literary scene 12 years ago. Can anyone else help?

Dear Mr. Phillips,

I am searching for a San Francisco author that seems to have left no traces on this earth. I have a book written by Mike Quin and published by The People's World of San Francisco. This book is called More Dangerous Thoughts and was copyrighted in 1941. It lists four other books that he wrote and the introduction was written by Theodore
Dreiser. I saw your website and thought perhaps your San Francisco background might have put you in touch with some info on him. I found his short stories and poems to be quite entertaining, but perhaps the rest of the world thought otherwise and has chosen to ignore him. In any case, if you can provide any information it would be greatly appreciated and if not thank you for your time.
