Abstract
Abstract A letter whose letter card consists of one or more plates of hard-paste china bearing one or more messages in the form of images, handwritten notes, proverbs, verses or the like. The envelope for the letter card consists of relatively stiff and shock-absorbent material, such as corrugated cardboard. Prior to introduction into the envelope, the letter card is placed into a recess formed in one side of an insert which snugly fits into the envelope and is also made of corrugated cardboard or a like shock-absorbent material to reduce the likelihood of chipping, breakage and/or other damage to the letter card during mailing or other mode of shipment to the recipient(s). The letter card can be assembled of two plates which are pivotally connected to each other by one or more flexible strips so that they can pivot relative to each other between first positions of full overlap preparatory to introduction into the envelope and second positions in which they are located in mutually inclined planes. The letter card can be placed on a table top, suspended on a wall, framed or otherwise set up for more or less permanent exhibition in a home, office, dormitory, military barracks or the like.
