FIELD OF THE INVENTION
The present invention relates to greeting card display systems.
BACKGROUND OF THE INVENTION
The custom of sending greeting cards can be traced back to ancient Chinese and Egyptian civilizations. By the 15th century, Europeans were printing New Year's greetings and with the continued advances in printing, the custom continued to gain in popularity. The first Christmas card was believed to have appeared in 1843 with mass production of greeting cards following shortly thereafter.
Often a receiver of a greeting card may wish to save, preserve or even display the greeting card in various manners. Some may wish to prop the greeting card up on a table, a desk, or a mantle, while others may store the greeting card in a box or photo album. The present invention features a greeting card display system that provides an aesthetically pleasing means of displaying greeting cards.
Any feature or combination of features described herein are included within the scope of the present invention provided that the features included in any such combination are not mutually inconsistent as will be apparent from the context, this specification, and the knowledge of one of ordinary skill in the art. Additional advantages and aspects of the present invention are apparent in the following detailed description and claims.
SUMMARY OF THE INVENTION

In some embodiments, the greeting card comprises a card front surface, a card back surface, a card first inside surface, and a card second inside surface. In some embodiments, the greeting card comprises a card top edge, a card bottom edge, a card first edge, a card second edge, and a card first crease from the card top edge to the card bottom edge.
In some embodiments, the card first panel is pivotally attached to the card second panel via the first crease. In some embodiments, the first crease divides the card front surface from the card back surface and the card first inside surface from the card second inside surface. In some embodiments, in a first open position, the card first inside surface is pivoted away from the card second inside surface. In some embodiments, in a second closed position, the card first inside surface is pivoted against the card second inside surface.
In some embodiments, the system comprises a protective sleeve having at least a sleeve first panel and a sleeve second panel. In some embodiments, the protective sleeve comprises a sleeve front surface, a sleeve back surface, a sleeve first inside surface, and a sleeve second inside surface. In some embodiments, the protective sleeve comprises a sleeve top edge, a sleeve bottom edge, a sleeve first edge, a sleeve second edge, and sleeve first inside and outside creases from the sleeve top edge to the sleeve bottom edge. In some embodiments, the protective sleeve comprises a sleeve cavity located therein from the sleeve top edge to the sleeve bottom edge and the sleeve first edge to the sleeve second edge. In some embodiments, the protective sleeve comprises a single sleeve opening fluidly connected to the sleeve cavity located on the sleeve top edge, the sleeve bottom edge, the sleeve first edge, or the sleeve second edge. In some embodiments, the single sleeve opening is adapted for insertion of the greeting card.
In some embodiments, the protective sleeve comprises at least three sealed edges located on any combination of the sleeve top edge, the sleeve bottom edge, the sleeve first edge, or the sleeve second edge. In some embodiments, the sleeve first panel is pivotally located on the sleeve second panel via the sleeve first inside crease and the sleeve first outside crease. In some embodiments, the sleeve first outside crease divides the front surface from the back surface and the sleeve first inside crease divides the first inside surface from the second inside surface. In some embodiments, the sleeve first inside crease and the first outside crease each lay on a plane, Plane A.
In some embodiments, in a first open position, the sleeve first inside surface is pivoted away from the sleeve second inside surface. In some embodiments, in a second closed position, the sleeve first inside surface is pivoted against the sleeve second inside surface. In some embodiments, in the first open position and the second dosed position, the sleeve first inside crease and the sleeve first outside crease each lay on Plane A. In some embodiments, the protective sleeve comprises a general shape of an envelope.
In some embodiments, the sleeve front surface, the sleeve first inside surface, and the sleeve second inside surface are transparent, semi-transparent or translucent. In some embodiments, the protective sleeve comprises a first attaching means located on a sleeve back surface thereon.
In some embodiments, the protective sleeve is moved into a first open position. In some embodiments, the greeting card is inserted into the sleeve cavity of the protective sleeve via the sleeve opening. In some embodiments, the protective sleeve is moved into a second closed position.
