The perforated stamp, Scott 728, is easily distinguished from the imperforate stamp cut from the souvenir
sheets. This design was issued as a Farley reprint only as a souvenir sheet, Scott 766. It is impossible to distinguish the
Farley Special Printing from the regularly issued souvenir sheet, Scott 730, by examining individual souvenir sheets, unless the
sheet has a margin of 13mm. That is, the distance between the stamps must be 13mm, as shown in the 766a
gutter pair above. This pair can
only be from the Farley special printing since a pair with this much spacing between stamps can not be made from the originally
issued souvenir sheets.
The Farley printing was issued as a full sheet of 225 stamps, with 9 panes of 25 stamps separated by 13 mm gutters. The stamp is often
collected as a pane of 25 stamps to retain the marginal markings of the originally issued souvenir sheet, as shown below. Single stamps,
or anything less than the full sheet for that matter, are given the suffix "a", that is either 730a or 766a. In the illustrated example
below, it can not be determined if the sheet is the original printing or the Farley Special Printing since there is no 13 mm wide margin
present. Therefore, the following sheet must be assumed to be the ordinary printing, Scott 730.
