An engraved self-portrait of Ottavio Leoni, bust length, turned towards the left; framed in a dodecagon. This print is lettered around the portrait: "Eques Octavi' Leonus Roman' pictor fecit / 1625 / Superiorum permissu". Trimmed to the platemark.

The print formed part of an album of portrait prints assembled by Cassiano dal Pozzo in Rome. Described in an early nineteenth-century inventory of prints in George III's library as Illustrious Painters &c:a, the album was dismantled later in the nineteenth century and its contents sold during the early twentieth century, when only a few of Cassiano's foreign non-royal portrait prints were retained for the collection.
