Antique map 'Insulae Divimartini et Vliarus vulgo l'isle de Re et Oleron'. Decorative map of Île de Ré and Île d'Oléron. This map originates from 'Atlas Novus, Sive Theatrum Orbis Orbis Terrarum: In quo Galliae, Helvetiae (\.)' by J. Janssonius (1656-1657). This piece is attributed to the mentioned designer/maker. It has no attribution mark and no official proof of authenticity, however it is well documented in design history. I take full responsibility for any authenticity issues arising from misattribution
