The American Bank Note Company Trade Sample Sheet
Produced as examples of the companies work and given out by salesmen.
These sheets were printed sometime before February 1879 when the ABN took over
printing stamps for the US Post Office.
The sheets were printed in 'fugitive' pastel colors that have tended to fade over time.
The colors can be divided into seven main color varieties;
Red, Violet, Green, Blue, Brown, Yellow, and Grey.
Red is the most common, followed by Violet. All main colors exist in numerous shades.
Most of the sheets have been cut up into single stamps. About 10 complete sheets are
thought to still exist, most of which have some sort of damage.
