"Graham's" may have been the first magazine in America to copyright each issue. By March 1842, "Graham's Magazine" was issuing 40,000 copies. This boom was reflective of a changing market in American readership. John Sartain believed its success was due to the appeal of the engravings he provided for each issue. "The Saturday Evening Post" reported that the August 1841 issue of "Graham's" cost $1,300 for these "embellishments". The "Post" reported April 30, 1842: "It is doubtful, if engravings of equal beauty ever adorned an American work". Typical engravings in "Graham's" included bridges, happy maids, and scenes which focused on peaceful domestic life and promoted marriage. The editorial staff grew to include "two lady editors", Ann S. Stephens and Emma Catherine Embury.
