About Optical Imaging Examples 1807 Rare Early American

CATOPTRICS (Optics - science) Issued New York: 1807; by J. Low Engraved by P. R. M.. Lovely and scarce early-19th century American engraving. This particular type of engraved printing process was very laborious, involving long-apprenticed highly trained hand artisans. It also involved challenging hand-operated machinery, inking of plates, sheets of paper individually hung to dry, skill, patience, and other endless tasks and labor. Because of these and various other factors, this printed leaf is an interesting original artifact from long past moment in printing.

In age worn condition, sheet age toned, scattered small spots or staining as clearly seen in scan -- overall still quite appealing visually. Could readily be displayed or collected. In all, remains a scarce and fascinating antique printed image any collector, dealer or institution would be pleased to own. Sheet measures c. 7 3/4" W x 9 3/4" H.
