Hugo Gernsback's Techni-Craft Publishing changed the title of SCIENTIFIC DETECTIVE MONTHLY to AMAZING DETECTIVE TALES in 1930. They published five issues under that name, with some very unusual cover art by John Ruger. Here are all five. Gernsback sold the magazine to Wallace Bamber, who published it from Fiction Stories, Inc., as AMAZING DETECTIVE STORIES, for five more issues in 1931. See wikivisually.
