This subseries section houses a wide variety of account journals and ledgers including approval journals; bound invoices; a cashbook that includes a listing for a special loan to Germain Seligman; one purchase book; and one indexed sales book listing artwork sold by de Hauke & Co., Inc. Also found are two general ledger books that list financial transactions and expenses by various accounts, including payments to Jacques Seligmann & Co., Inc., for furniture and installation, general expense accounts, payments to galleries and individuals, and sales of works of art.

This subseries section houses bound and loose invoices, including sales, consignment, and consular invoices and one volume of balance sheets and profit/loss statements. Similar to the invoices arranged in the Financial Files and Shipping Records (Series 7) of Jacques Seligmann & Co., Inc., the invoices are arranged in bound volumes chronologically and in loose format alphabetically by client. The bound and loose miscellaneous invoices are for sundry expenses. The consignment invoices and other documentation in the file detail works of art on consignment to the Paris office of Jacques Seligmann & Co. or to individual clients. The consular invoices were required by foreign governments for import to the United States, and every work of art had to be listed and declared for customs approval. All of the invoices contain important provenance information.

Shipping records within this subseries reflect the high level of sales activity engaged in by de Hauke & Co., Inc., during the late 1920s and early 1930s. The shipping records provide useful documentation of the movement of works of art in Europe and to the United States. Complex arrangements with shippers, packers, and customs officials were arranged through frequent and detailed correspondence.

One file contains miscellaneous credit notes, lists, and other documentation regarding sales and banking transactions.
