Mc Elroys Philadelphia City Directory - 1842 - William Norris

Advertisement for the Philadelphia workshops of William Norris, a prominent early locomotive builder in the United States, who made locomotives for both American railways and exported to railways in Britain.
Note that the "cut" (illustration) appears to be a generic one, and while typical of the 4-2-0 locomotives of the period, may not reflect a particular locomotive built by Norris; the same illustration was used on a Baldwin ad on the previous page of the same directory.

Note: image has been significantly lightened from its original so as to be visible.
