Although we always associate H. H. Warner with Rochester, as an agent for Mosler & Bahmann & Co., he appears to have had a presence in other major cities. To be sure, he was selling safes in Rochester as is amply demonstrated by my last post; however, he also seems to have been in a number of other cities including Cincinnati and Chicago among others. This is demostrated by this ad that appeared in the 1873 Chicago City Directory.
The ad is for Warner, Howard & Co. at 51 State Street. No telling who Mr. Howard was, but there can be little doubt that the Warner was our resident entrepeneur and patent medicine mogul, Hulbert Harrington Warner.
