FSC real wood frame with double mounted 16x12 print. Double mounted with white conservation mountboard. Frame moulding comprises stained composite natural wood veneers (Finger Jointed Pine) 39mm wide by 21mm thick. Archival quality Fujifilm CA photo paper mounted onto 1mm card. Overall outside dimensions are 23x19 inches (584x482mm). Rear features Framing tape to cover staples, 50mm Hanger plate, cork bumpers. Glazed with durable thick 2mm Acrylic to provide a virtually unbreakable glass-like finish. Acrylic Glass is far safer, more flexible and much lighter than typical mineral glass. Moreover, its higher translucency makes it a perfect carrier for photo prints. Acrylic allows a little more light to penetrate the surface than conventional glass and absorbs UV rays so that the image and the picture quality doesn't suffer under direct sunlight even after many years. Easily cleaned with a damp cloth. Please note that, to prevent the paper falling through the mount window and to prevent cropping of the original artwork, the visible print may be slightly smaller to allow the paper to be securely attached to the mount without any white edging showing and to match the aspect ratio of the original artwork.

EDITORS COMMENTS
This 16th century photograph depicts the Ballestilla, also known as the Jacob's staff or Ballestina, an intriguing navigational instrument housed at the Maria Pita House Museum in Corunna, Galicia, Spain. The Ballestilla was a vital tool for seafarers during the Age of Discovery, enabling them to calculate the height of the sun and other celestial bodies above the horizon for determining latitude and navigational positioning at sea. Crafted from wood, this exquisite object features a cross staff with graduated scales, allowing mariners to take precise measurements. The Ballestilla's historical significance lies in its role as a precursor to more advanced astronomical instruments, such as the sextant, which revolutionized navigation in the centuries that followed. The interior of the museum showcases this remarkable artifact, preserving it for future generations to appreciate the ingenuity and resourcefulness of the seafaring communities of the past. The Ballestilla is a testament to the rich maritime history of Spain, particularly in the region of Galicia, which was a hub for exploration and trade during the 16th century. This photograph offers a glimpse into the past, transporting us back to a time when navigators relied on their wits, their knowledge of the stars, and their trusty instruments to traverse the vast oceans and expand the horizons of human exploration.
