The Rare Books and Manuscripts Div. of NYPL (212-930-0801) has an atlas
published by W. Holtrop in Amsterdam, thought to be from the 1790s. It
includes maps engraved in the 1780s. It is a small atlas, 14 cm. high. The
classmark of the atlas is *KF 179- Holtrop. (I haven't looked at it to see if
it contains your map.) Holtrop's dates are given as 1751-1835 in NYPL's
retrospective catalog.
