The large numbers inside the Maps are for facilitating the use of the twelve square Star Charts, each number indicating the position of the sky, of the centre of its corresponding Chart." • Highest Quality Giclée Print • 255gsm Heavyweight Premium 100% Cotton Archival Fine Art Paper • Fine Art Print - Not a Poster! • Archival Pigment Ink • Made in Los Angeles, USA
