There is no accurate issue record of this stamp as its existence was not known until almost two years after the approximate date of issue, when this variety was discovered by a collector who claimed to have had a copy in his collection "for about one year." Upon investigation it was discovered that in May 1924 the Bureau used some unperforated coil waste made from sidewise rotary press sheets and had put these through the flat plate perforating machines, hence these appeared perforated 11 both horizontally and vertically.
As there was no knowledge of this stamp having been issued and since the perforations were the same as the ordinary stamp they were entirely overlooked, the only copies known to have been saved were accidental rather than intentional.
This variety was never delivered to the Philatelic Agency, all copies were sent out with the regular stock of one cent stamps, almost all known copies have been found from mail originating in New York City. It has been said that only seventeen copies in mint condition is known and only eighty eight used copies have been
found to survive,
It is best not to identify the width of #594 by measurement. A better method is to take an inexpensive #597, cut the corners off and place it on top of #594. As you can see from the illustration above the edge of the frames are exactly the same width and height.
Three postcards (example above) and two covers are recorded for this issue
