Context paragraphs:
Revenue stamps of Malta: Malta first issued revenue stamps in 1899, when the island was a British colony.  From that year to 1912, all revenue issues were postage stamps overprinted accordingly, with the overprinting being done either locally or by De La Rue in London.  Postage stamps also became valid for fiscal use from 1912–13, so no new revenues were issued until 1925–30, when a series of key type stamps depicting King George V were issued.  These exist unappropriated for use as general-duty revenues, or with additional inscriptions indicating a specific use (Applications, Contracts, Registers or Stocks & Shares).  The only other revenues after this series were £1 stamps issued in 1941, 1948 and 1954.  Postage stamps remained valid for fiscal use until at least the 1970s.

Pre-adhesive mail: Pre-adhesive mail, also called pre-stamp mail, are letters carried in mail systems before the issuance of postage stamps.  A stampless cover is another description and generally also refers to any item of mail sent before the issuance of postage stamps but it can also refer to mail sent, after the introduction of postage stamps, unpaid (as was permitted in many countries) or without the pre-payment being indicated by the affixing of a postage stamp; it could have been pre-paid in cash and marked paid.

Postage stamps and postal history of Israel: The postage stamps and postal history of Israel is a survey of the postage stamps issued by the state of Israel, and its postal history, since independence was proclaimed on May 14, 1948.

Jonah Matranga: Jonah Rzadzinski Matranga (born Jonah Sonz Matranga, August 11, 1969, Brookline, Massachusetts) is a singer, songwriter, and guitarist who has released a variety of solo material under his own name and onelinedrawing, and has previously been part of the bands Far and New End Original (an anagram of "onelinedrawing") and Gratitude.  He now continues to work and tour under onelinedrawing'.

Gratitude (band): Gratitude was formed in 2003 by Mark Weinberg (originally of the band Crumb) and Thomas Becker (originally of the Get Up Kids).  Initially called the Collision, the band was joined by Bob Lindsey on bass and Robby Cronholm (also formerly of Crumb) on vocals.  After touring in 2002 with New End Original, which featured Far alum Jonah Matranga and Jeremy Tappero, Cronholm left the band and was replaced by Matranga.  When Matranga joined, the band changed their name from the Collision to Gratitude.  After picking up Matranga and changing their name, Gratitude signed to Atlantic Records.  The group picked up Tappero as second guitarist before going into the studio.  After Becker left the band in the middle of recording the record, Drummer David Jarnstrom joined the band before the release of their self-titled debut album (Becker and other session musicians fulfilled the drum role during the recording of the album).  Atlantic Records released "Gratitude" on March 8, 2005.  The tracks "Drive Away" and "This Is the Part", were released as singles and received significant radio play both in the US and the UK.  Gratitude's first tour for the album was a North American tour supporting Jimmy Eat World (to whom the band has often been compared), and they were also on the bill for the 2005 Warped Tour and a leg of the 2005 Taste of Chaos.

List of postage stamps of India: India has a long and varied postal history and has produced a large number of postage stamps.  These have been produced by a variety of techniques including line engraving, typography, lithography, photogravure and web-offset.  Stamps have been produced both for postage and for service or revenue.  Definitives and commemoratives have been issued.  Stamps have been produced both as unperforated sheets, perforated and miniature sheets.  The stamps have been produced in a number of shapes - the Scinde Dawk being rounded and some, like the stamp on the Bombay Sappers being triangular.  Recently the 2009 stamp on Louis Braille had braille imprinting on it in addition.  Many cases of overprinting exist - for converting the use of domestic postage stamps to service; to earmark stamps sold by field post offices attached with international control commissions and other reasons.
