209 pages of xeroxed copies. 7 5/8” x 9 7/8”. The "original" drawings are likely located in private collections or with the descendants of the families from whom they were collected, as the 1980 publication by Hooykaas features copies and reproductions, rather than the source drawings themselves. While the publication serves as a scholarly record, it does not represent the physical location of the original drawings which are not in a single, publicly documented repository. Condition is VG+ with some wear to head of spine. Clean text.
