Abstract
Abstract A device and method for transmitting selected confidential information from an institution to a plurality of parties using post cards that have a preprinted camouflage pattern printed in a first predetermined color, confidential information imprinted in a second predetermined color by the institution, printing the name and address of each second party on their respective card, sending the card through the mail to each second party and the second party viewing the information through a filter medium that freely transmits the first predetermined color and renders the information printed in the second color darker than the camouflage pattern. The card may be formed by printing the confidential information on a continuous form printer then detaching individual sections, folding in half and securing the halves together to fabricate a postcard sized and thickness form and then mailing the form to the respective second party at post card postage rates.
