The editorial work was largely done by Sloane, but Gernsback retained final say over the fiction content. Two consultants, Conrad A. Brandt and Wilbur C. Whitehead, were hired to help find fiction to reprint. Frank R. Paul, who had worked with Gernsback as early as 1914, became the cover artist; Paul had produced many illustrations for the fiction in "The Electrical Experimenter". "Amazing" was issued in the large bedsheet format, 8.5 × 11.75 in (216 × 298 mm), the same size as the technical magazines. It was an immediate success and by the following March reached a circulation of 150,000.
