A tag from an insured parcel post package sent to zone 4 in 1940. There are two possible combinations of postage and insurance which produce fifty cents, though the possibility is that the sender made a convenience overpayment. Assuming the sender paid an exact rate, the package could have weighed seven to eight pounds with insurance from $25.01 to $50.00 or ten to eleven pounds with insurance up to $5.00
