Format
These gummed souvenir sheets had an unusually large format of 7½"x9" (190mmx229mm). The top left hand corner sported the decade in a number format, the entire background of the sheet was devoted a specific event of that decade (e.g. the Wright brothers standing next to their Flyer II on the 1900s sheet.)
The fifteen stamps were printed at an angle of 8°, the horizontal perforations ran from the stamps up to the edge of sheet. The stamps were arranged on the sheets in four rows, and nested in arrangements unique to each sheet. An area was devoted to the description of the decade as depicted by the stamps on it. The description of each stamp was printed on the gummed side of the sheet, behind each stamp.
The words Arts, Sports, Historical Events ran on the left hand edge, Technology, Entertainment, Science ran on the top edge, Political Figures, Life Style on the right hand edge of the sheet.
