The Minkus catalogue was a comprehensive catalogue of American and worldwide postage stamps, edited by George A Tlamsa and published by Krause Publications.
 In the United States Minkus competed with the Scott catalogue as a distant second.
 Generally sold through department store stamp collecting departments, it had its own system of numbering stamps which was used in its catalogues and stamp albums; Scott's numbering system is proprietary.
 The Minkus catalogue and numbering system was acquired by Amos Press in 2004 and no further editions were published.
 The last US catalog was the "2004 Krause-Minkus Standard Catalog of U.S. Stamps".
Granville Richard Francis Tompkins CBE (15 May 1918 – 6 December 1992) was a print, advertising and retail entrepreneur, best known for founding the Green Shield Stamps company, as well as the Argos chain of catalogue stores which became one of the largest retailers in the United Kingdom, and a constituent of the FTSE 100 Index.
Green Shield Stamps was a British sales promotion scheme that rewarded shoppers with stamps that could be used to buy gifts from a catalogue or from any affiliated retailer.
 The scheme was introduced in 1958 by Richard Tompkins, who had noticed the success of the long-established Sperry & Hutchinson Green Stamps in America.
The 1930 "Graf Zeppelin" stamps were a set of three airmail postage stamps, each depicting the image of the "Graf Zeppelin" airship, exclusively issued by the United States Post Office Department, USPOD, in 1930 for delivery of mail carried aboard that airship.
 Although the stamps were valid for postage shipped via the Zeppelin Pan American flight from Germany to the United States, via Brazil, the set was marketed to collectors and was largely intended to promote the route.
 93.5% of the revenue generated by the sale of these stamps went to the Zeppelin Airship Works in Germany.
 The stamps were also issued as a gesture of good will toward Germany.
 The three stamps were used briefly and then withdrawn from sale where the remainder of the stock was destroyed by the Post Office.
 Due to the great depression and the high cost of the stamps most collectors and the general public could not afford to purchase or use them.
 Consequently, only about 227,000 of the stamps were sold, just 7% of the total made, making them relatively scarce and highly prized by collectors.
The Scott Catalogue of postage stamps, published by Scott Publishing Co, a subsidiary of Amos Media, is updated annually and lists all the stamps of the entire world which its editors recognize as issued for postal purposes.
 It is published in eight large volumes (as of 2015) that include six volumes containing all the countries of the world that have ever issued postage stamps, the "United States Specialized Catalog", and the "1840-1940 Classic Specialized Catalogue" (covering the world for the first 100 years that stamps were issued).
 It is also produced in non-printable CD and DVD editions.
 The numbering system used by Scott to identify stamps is dominant among stamp collectors in the United States, Canada and Mexico.
War on Terror, The Boardgame is a satirical, strategic board game, produced and published in 2006 by TerrorBull Games.
 "War on Terror" was originally conceived in 2003 by Andy Tompkins and Andrew Sheerin, two friends based in Cambridge, England.
 The initial inspiration for the game came from the imminent Invasion of Iraq but, as a whole, was intended as a reaction and challenge to the counter-productive pursuit of the wider War on Terror.
 In 2005, Sheerin and Tompkins founded TerrorBull Games and gathered enough financial support from a mixture of friends and acquaintances to put "War on Terror" into production.
Matched pair testing is used to detect discrimination.
 The focus is to determine the presence of disparate treatment in the offering of goods and services during the sales process.
 Traditionally used to determine discrimination in housing and mortgage lending, the research methodology involves the use of pairs of testers or mystery shoppers, representing test and control cells.
 Control cells usually comprise non-protected classes of consumers and test cells comprise protected classes of consumers under the Fair Housing Act.
 For example, control cells comprise non-minority or male mystery shoppers while test cells comprise African American or Hispanic or female mystery shoppers.
 The mystery shoppers in each pair (e.g., African American and White) conduct the tests separately but each is provided with profiles that are matched or very similar.
 The profiles typically contain financial, demographic and classification characteristics (gender and age) of the shopper.
 The shoppers in each pair perform the same inquiry and ask for the same information.
 The only difference is the test treatment, for example, the ethnicity or gender of the mystery shoppers.
 Prior to conducting the mystery shop, the mystery shoppers are trained on how to conduct the mystery shops, the use of the profile and how to record information pertaining to the treatment and information they will receive.
 After completing the mystery shop, the shoppers record the experience encountered and the information received on a questionnaire.
 The information entered on the questionnaires is entered into an electronic data base and the experiences of test and control mystery shoppers are compared.
Acceptance in lieu (AiL) is a provision in British tax law under which inheritance tax debts can be written off in exchange for the acquisition of objects of national importance.
 It was originally established by Chancellor of the Exchequer David Lloyd George as a means for the wealthy to pay the increased estate taxes imposed by his People's Budget of 1909 but had its roots in similar schemes dating to the late 19th century.
 It has developed from the early years when it was used mainly as a means for the aristocracy to dispose of country estates to the National Trust to the modern day when it is more associated with the transfer of works of art, antiquities and archive material to museums.
 The scheme is administered by Arts Council England, a non-departmental public body of the Department for Culture, Media and Sport.
 The scheme has brought many houses, works of art and other collections into publicly accessible institutions when they would otherwise have gone to auction.
 In April 2013 the Cultural Gifts Scheme was started which allows taxpayers to make a donation of art in return for a credit on income tax, capital gains tax or corporation tax.
 The Cultural Gifts Scheme is also administered by Arts Council England and is reported jointly with the Acceptance in Lieu scheme.
