6 original copperplate engravings showing things pertaining to microscopes.
From an early edition of The Encycopedia Britannica.
Date: 1797.
Engraved by A. Bell (1726-1809)
Black and white.
Size: 26.5 x 20.5 cms or 10 1/2 x 8 inches.
Condition: Very Good. There are a few spots of foxing, or blackish matter, across the surface of the plates. The foxing tends to be located close to the left hand edge so might be hidden were they to be framed. The left hand edge of each, at the point where the plate has been removed from the encyclopedia, has browned. The plates are otherwise clean and remarkably fresh.
There is a seventh plate in this collection that I will include but have not charged for since it is printed way off center and so can only be of use for reference.
