K. & E. Color Analyzer
A 1925 sales pamphlet for the K. & E. Color Analyzer, a direct-reading spectrophotometer, issued by Keuffel & Esser Co. of New York and Hoboken for chemists, lab supervisors and instrument buyers. The single indexed image is the printed wrapper: a thin double-rule border on tan stock enclosing centered letterpress lines in graded sizes, closing with a row of branch-city addresses in small caps and a one-line list of goods sold.
