5.5x8.5” quality library binding with leather spine and cloth bound boards. A collection of erotic and sexually explicit bw illustrations with gilt pages. Title and “Cinquante Planches” name which we believe to be publisher as well as 1790 date in gold gilt lettering on spine that we believe to be an early 1900s printing. Book is missing title page if it indeed had one. Illustrations are all set during the late 1700s and feature nude men and women engaged in various sexual antics including men with women and women with women. One illustration shows black woman with white man, an unspoken theme at the time. Clothbound boards show some traces of insect damage on front cover and back cover has wear along top of book. Fine with choice/Exc. pages.
