Series IV. Orders contains order forms and order index cards circa 1940 to 1985. Orders, estimators' worksheets (in Series V.), and recaps (in Series VI.) are stamped in the upper right corner with an order number, which appears to correspond between records. The index cards located in this series correlate client names, job order numbers and dates and may be used to reference specific print jobs. Though dates are not present on all order forms, bundles of sheets were dated on the outer packaging.
