At first thought, the average person does not realize the scope of the words “questioned document.” One envisions a signature on a will, a check, or a contract. Only after careful consideration does he realize that a typewritten letter, dollar bill, postage stamp, gas station receipt, airline ticket, and even the brand on the side of a cow roaming the range can be a “questioned document.” In the broadest, all-encompassing terms, a document is any fixed method of communication between one individual and another.
