VERY FINE APPEARANCE. ONE OF FIVE RECORDED EXAMPLES OF THE "CAMMANN" IMPRINT ON THE 10-CENT ROSE OR CARMINE LITHOGRAPH. A FASCINATING GENERAL ISSUE VARIETY.
Research by Everett Cooper (published in the Confederate Philatelist, Jan.-Feb. 1985) established that Cammann was indeed a lithographic worker, but Cooper connected the "Cammann" imprint to work performed for J. T. Paterson (two Confederate banknotes printed by J. T. Paterson and bearing the Cammann imprint were offered in Sale 1071, lot 4518). It is known that the Paterson firm acquired some of Hoyer & Ludwig's equipment and employed a number of lithographers who had previously worked for Hoyer & Ludwig. The 5c Blue and 10c Rose lithographed stamps, which have always been attributed exclusively to Hoyer & Ludwig, could well have been printed by both Hoyer & Ludwig and J. T. Paterson, with the Hoyer & Ludwig imprint on the 10c stone left unchanged during the later Paterson printings. The addition of the "Cammann" imprint on 5c Blue and 10c Rose stamps tends to support Cooper's theory that a portion of the printing took place at the Paterson firm.
This stamp is the basis of the illustration in the 1929 Dietz book (p. 119). Ex Knapp, Hall and Freeman. With 2014 P.F. certificate as "Carmine Rose"
