HISTORY AND COMMENTARY
In 1919 a plan was launched to salvage the leading or trailing scraps left over from rotary press printings by turning them into sheet stamps for distribution. Coil waste was perforated 10 in one direction on the rotary press perforator. It was then perforated 11 in the other direction, using the line perforator normally used for flat-plate printings, producing Scott 538, 539 and 540. The unfinished horizontally imperforate sheets (Scott Nos. 538a and 540a) were acquired by Edward C. Worden, who sold them through J. M. Bartels in 1922.
