Libellus recollectorius auctoritatum de veritate conceptionis beatae virginis Mariae
This is a 1475 Latin devotional tract on the Immaculate Conception, printed in Milan by Christophorus Valdarfer and later owned by Ercole Silva, held by the Boston Public Library. The single picture is a bookplate-style scan rather than a text illustration: a circular engraved seal inside a laurel wreath, with a bookseller's accession number and a line naming the James Jackson Storrow (Harvard '57) Fund beneath it. A designer might take from it the classical wreath-and-medallion framing typical of nineteenth-century library ex libris marks.
