Ian Macky says: “Published in 1935, the Secret Museum is a mystery book. It has no author or credits, no copyright, no date, no page numbers, no index. Published by ‘Manhattan House’ and sold by ‘Metro Publications,’ both of New York, its ‘Five Volumes in One’ was pure hype: it had never been released in any other form.”
Three million cheers to Macky for not only scanning all 564 pages of this treasure of a book, but for cleaning up the images, transcribing the text, and adding thumbnail galleries and a copy of a 1942 magazine ad.
