ABSTRACT:
A display device comprises a rectangular transparent plastic envelope formed from two sheets of flexible plastic material which are seamed together adjacent their top, one side and bottom margins. The sheets also include horizontal enclosed sleeves at the top and bottom of the envelope in which tubular arms are located. Flexible coupling means are provided in engagement with the upper tubular arm while the lower tubular arm is engaged by laterally spaced tension means which permit the lower arm to turn ninety degrees with respect to the upper arm. A zipper-type closure means may be provided along the open side of the envelope to removably seal the envelope.
