context_page_description: In philately, the term cover pertains to the outside of an envelope or package with an address, typically with postage stamps that have been cancelled and is a term generally used among stamp and postal history collectors. The term does not include the contents of the letter or package, although they may add interest to the item if still present. Cover collecting plays an important role in postal history as many covers bear stamps, postmarks and other markings along with names and addresses all of which help to place a cover at a given time and place in history.
context_section_description: The term originates from the practice of covering a letter by folding a separate sheet about it to physically protect it and prevent infringement of confidentiality. In the first half of the 19th century it became the fashion to cut the cover into a diamond or lozenge shape. This was the precursor of the version of the envelope known today. Its convenience and popularity led to the lozenge design being adopted for the special pre-paid postage envelopes and covers issued in 1840 after postal reforms were introduced by Rowland Hill and others.
  A philatelic cover is an envelope or post card prepared with a stamp(s) and address and sent through the mail delivery system for the purpose of creating a collectible item.
