Highly unusual miniature botanical leporello. N.d., mid-19th century. No publisher or other information regarding its origin. Closed, 4 by 3 cm, and when fully opened up, 69 cm wide. 22 panels with hand-colored botanical plates -- each representing a different class of flower -- plus the gilt foil covers. Title "Table of the Classes" is cut out and pasted onto the gilt foil cover. Classes include monandria, diandria, triandria, tetrandria, et. al. The leporello might be a homemade book, using printed hand-colored vignettes taken from another, unknown source, but we tend to believe that it was issued as such, notwithstanding the improvisation quality of the front cover and the unconventional materials used. We could find no other copy of this on OCLC or elsewhere, but admittedly the sparse information about it makes it challenging to search for. We are comfortable asserting, though, that the leporello is truly rare, if not one-of-a-kind, and further, that as a teaching tool and botanical it is a most unusual format. Backed by blue cloth, which has some wear. Some of the folds are tender, and the leporello, when closed, doesn't stack up entirely straight.
