First published in hardback as Revelations in Black in 1947, this British paperback contains 11 of Jacobi's best horror stories frm Weird Tales, Amazing Stories, Thrilling Wonder Stories and other pulp magazines of the 1930s. 144 pages. Just light exterior edge wear, some back cover rubbing, moderate toning of pages, but no markings. Jacobi's books are now out of print and are thus becoming scarce.
