ABSTRACT:
A blank which may be erected to form a security shield for public telephones to guard against unauthorized visual access and theft of telephone calling card numbers and information. The blank includes a plurality of hingedly connected panels, and retention slots which engage cradle posts in a conventional telephone housing. A telephone security feature is provided by dimensioning the shield so that it extends around the periphery of the key pad and limits visual access to the user. The shield panels fold into a compact arrangement of overlying panels to facilitate its ready storage and accessibility to the user.
