De magia liber / Antonii de Haen.
A Latin treatise on magic by Anton de Haen, printed in Leipzig in 1775 by I. P. Kravs for a scholarly readership. The picture is a decorative printed border strip of scrolling acanthus leaves, shells and a central motif of trumpets crossed behind a shield-like cartouche, showing how eighteenth-century printers framed type. A designer could take its symmetrical scrollwork and bilateral ornament as a model for a narrow header or divider band.
