Daybooks and ledgers documenting Covert's finances and possibly his work as a travelling salesman for the Vesuvius Crucible Company. One ledger relates to the estate of Mary I. Covert, his mother. These financial records are comprised primarily of cryptographic entries seemingly recorded in a code based on Covert's Social Security number, the key to which is available in the "Word and number puzzles" Series. The daybooks also contain scattered original watercolors, ink sketches, and other artwork.
