For those who may not know what an 'essay' stamp is, here is Wiki's explanation: In philately (stamp collecting), an essay is a design for a proposed stamp submitted to the postal authorities for consideration but not used, or used after alterations have been made.[SUP][1][/SUP][SUP][2][/SUP] By contrast, a proof is a trial printing of an accepted stamp. Both essays and proofs are rare, as usually just a few are produced. Although intended for internal use by printers and official bodies, essays sometimes find their way onto the philatelic market.
