This original July 1, 1901 monthly statement connects the manufacturing firm of Abendroth Brothers of Port Chester, Westchester County, New York, with the Hon. W.S. Jenks of 717 Seventeenth Street Northwest, Washington, D.C. The document is a pre-printed commercial form, filled out by hand in blue ink on the front, with additional pencil calculations on the reverse. It represents a surviving record of early twentieth-century business accounting, issued by a company known for producing stoves, ranges, and furnaces. The recipient’s title, “Hon.,” suggests a person of standing, likely a judge or elected official, which adds a layer of historical interest for researchers of Washington, D.C. social and political circles of the period. The front of the statement lists a carried balance from 1900 of 282, followed by entries dated February 28 and March 7 with amounts of 2565 and 550, leading to a prominent total of $3397. Further itemized figures appear below, including 52.25, 54.26, 706.51, 135.99, 106.51, 29.48, and 54.26, reflecting specific charges, credits, or adjustments within the account. A handwritten number, 508, appears in the upper left corner, likely serving as an internal invoice or statement number. The reverse side contains additional calculations in pencil, with notations such as “till July 23,” “till July 6,” and “deduct of 1.50 on 25 stc,” along with arithmetic equations like 66.25 minus 3.75 equals 62.50 and 85.75 minus 6.25 equals 79.50. These markings provide a rare glimpse into the detailed, back-office processes of a turn-of-the-century commercial transaction. As an original piece of American business ephemera, this statement will appeal to collectors of industrial history, vintage paperwork, Westchester County memorabilia, or documents connected to Washington, D.C. The Abendroth Brothers name carries weight in the history of heating equipment manufacturing, and this piece ties that legacy to a specific individual and address. The paper has aged naturally to a warm cream tone, with light tanning and minor foxing consistent with its age. A prominent horizontal fold runs across the center of the front page, and there are a few minor creases, but no significant tears, rips, or stains are evident. Both the blue ink and pencil handwriting remain clear and fully legible, preserving all the original financial data for study or display. This is an authentic, unmodified historical document, ideal for archival collections, historical research, or as a distinctive gift for anyone interested in the commercial life of the United States at the dawn of the twentieth century.
