https://www.swanngalleries.com/auction-lot/black-sun-press.-crosby-harry.-the-mad-queen._9keoimv6zz A copy sold for $373.00 in 1994. I assume it is worth more now. There was a 1976 biography of him that pumped up interest in him. https://www.amazon.com/Black-Sun-Transit-Violent-Classics/dp/1590170660#:~:text=An%20acclaimed%20novelist%2C%20essayist%2C%20biographer,the%20legendary%20icon%20of%20adventure. I am not sure that interest is still as high but the biography is still in print.
