Special printing of the 1¢ Fort Dearborn – Century of Progress – Pane of 25 – Issued without gum.
On sale at the Philatelic Agency in Washington, D.C. from March 15 through June 15, 1935.
It would be impossible to distinguish the Farley Special Printing from the regularly issued souvenir sheet by examining individual stamps, unless the stamp or pane has a wide margin. The distance between the stamps in the pair shown is 13 mm. This pair can only be the special printing since a pair with this much spacing between stamps can not be made from the originally issued panes. Any difference in shade is incidental.

The special printing of the one cent Fort Dearborn, Century of Progress stamp was issued as a full sheet of 225 stamps. It was printed by the flat plate method, 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. In this case it can not be determined if the illustrated 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. Note the manner in which the pane was trimmed from the original sheet of nine panes. This even trimming forms four nearly equal margins on the pane. This is the way in which the original souvenir sheets were sold.
