No coloured paper can be received for stamping, nor any paper which is too thin to bear the impression of the dies. 7th. Envelopes provided by the office, with the proper stamps thereon, will be substituted for any which may be spoiled in the operation of stamping. A recent concession made by the Board of Inland Revenue may be regarded as one of the latest novelties in the advertising world. Under the arrangement in question, the Stamp-Office permits embossed rings with the name of a particular firm, e. g. "Allsop & Co., Burton-on-Trent," "De la Rue & Co.," to be placed round the stamp as a border to it. In 1844, after the exposé of the letter-opening practices at the General Post-Office, Mr. Leech gave in Punch his "Anti-Graham Envelopes," and his satirical postage envelope, afterwards engraved by Mr. W. J. Linton, and widely circulated, represents Sir James Graham sitting as "Britannia." About the same time there might have been seen in the windows of booksellers of the less respectable class, a kind of padlock envelope, exhibiting the motto, "Not to be Grahamed."
