1856 1d and 3d Diadems: 1854 original estimate prepared by Postmaster-General Raymond for the procurement of steel printing plates plus printing inks from England for 1d and 3d postage stamps. Affixed in the margin of the first page are unused examples of the 1d Orange-vermilion and 3d Yellow-green Wmk Numerals of Value (1d fine with margins all round, 3d touched at right). Some splitting along folds and some repairs have been made to some tears, nevertheless a remarkable and highly significant document. This estimate was forwarded to Messrs Perkins Bacon & Co. who provided tenders for the two stamps, resulting in the production of the 1d and 3d Diadems.
