Imprimatur Sheets
When sheets of the Penny Black were first printed various postal and other officials took the liberty of removing various numbers of stamps from their sheets to present as gifts to dignitaries and other important people. These sheet portions are commonly referred to by collectors as "imprimaturs" or "imprimatur sheets". There are approximately 850 of these sheet portions in the British Postal Museum which also include overprints for British Bechuanaland, Oil Rivers, Levant and Zululand and also departmental overprints such as Army and Inland Revenue.

Famous quotes containing the word sheets:
“Why make so much of fragmentary blue
In here and there a bird, or butterfly,
Or flower, or wearing-stone, or open eye,
When heaven presents in sheets the solid hue?”
—Robert Frost (1874–1963)
