The "Fictioneers" "Black Mask" Magazine Check to H. H. Stinson January 22, 1945 " A Noose for Little Nemo"

I was thrilled to find this check online and purchase it. Herbert Hunter Stinson was a writer who was married to my cousin Evelyn Nichols Stinson (actress in her sister's play "Abie's Irish Rose"). Anne Nichols, the playwright, collaborated with her brother-in-law on many ventures.
H. H. Stinson was one of the famous "Fictioneers" or "Black Mask" boys writing for "Black Mask" magazine in the 1930s/1940s.
Photo #1 is the check that he received on January 22, 1945 through his infamous agent, Jacques Chambrun. Photo #2 has his cover story "A Noose for Little Nemo." Photo #3 is the back of the check endorsed by Jacques Chambrun.
Photo #4 was sent to me by my cousin (daughter of H.H. Stinson) and shows the First "Fictioneers" meeting January 11, 1936:

Earl Stanley Gardner was also one of the Fictioneers.
Jacques Chambrun, the notorious agent who endorsed this check was quite the character. The following is from the internet:

Jacques Chambrun was a New York-based literary agent in the nineteen-forties and fifties with a penchant for pinstripe suits and stealing his clients’ money. Chambrun embezzled thirty thousand dollars from W. Somerset Maugham by secretly negotiating the world rights to his books. When Ben Hecht ghost-wrote Marilyn Monroe’s memoir, Chambrun sold a scandalous passage to a London tabloid for a thousand pounds with neither Monroe nor Hecht’s permission; Monroe was so unnerved by the article that she rescinded her support for the book and Hecht had to return his five-thousand-dollar advance to Doubleday. (“My Story” was eventually published, twenty years later, but Hecht was not credited until the book’s third printing.)
