For when, like, your usual horse just isn't doing it for you anymore and you need a horse glow-up ... it's the American Horse Exchange.
This undated (ca. 1900?) photograph of the American Horse Exchange, once located at 7th Avenue and 50th Street, New York, N.Y. is from Hagley Library's collection of Warren-Ehret Company photograph albums (2002.251).
The Warren-Ehret Company was a forerunner in the composite roofing industry, formed in 1883 in Philadelphia and incorporated in 1887. It has antecedents in the patents and business acumen of two people. Those are Samuel Warren (b. 1822) who has been called the "father of the modern roofing contracting industry" and Michael Ehret (b. 1845) who patented his slag (or cinder) roofing system in 1868.
A detailed history of these men and further company history, as well as background on the roofing industry in America, is found in "One Hundred Years of Roofing in America" published by the National Roofing Contractors Association.
