Size: 66mm x 240mm (Item No. 66/24)
The Showgard 66mm x 240mm Black Mount is a specialized size within the "Strips for Souvenir Sheets" range. This height is particularly useful for taller souvenir sheets and large vertical blocks that require more clearance than the standard 63mm series. The deep black background provides the classic "Showgard look," creating a high-contrast frame that makes stamp colors vibrant and perforations clearly defined.
Sophisticated Black Framing: The opaque black backing provides a professional, museum-quality border, hiding the album page behind the stamp and focusing the eye on the philatelic item.
Archival Preservation: Crafted from 100% oriented polystyrene, these mounts are chemically inert. They are completely acid-free and contain no plasticizers, ensuring your stamps’ gum and ink are protected from long-term damage.
Specialized 240mm Length: This mid-range length is ideal for international souvenir sheets that exceed the standard 215mm strip length but do not require the full 264mm of the "Accommodation Range."
Twin-Seam Security: Features the patented Showgard parallel welds at the top and bottom. This design holds the sheet securely while allowing air to circulate, preventing the "sweating" that can lead to toning or gum disturbance.
Anti-Reflective Front Foil: The crystal-clear front is treated with a specialized matte finish to eliminate "Newton rings" and reduce glare from overhead lighting.

Since 1959, Showgard has been the definitive choice for serious philatelists. These mounts provide a permanent, waterproof, and shrink-proof barrier against the elements—protecting your collection from dust, humidity, and the natural oils from human handling.
Pro Tip: To achieve a custom fit, use a Showgard Guillotine to trim the width of the 240mm strip. For a 66mm tall sheet, always ensure you leave a tiny margin of roughly 1mm at the top and bottom to allow for the natural expansion and contraction of the paper.
