Lighthouse SF Supplement United States - Sheetlets
Lighthouse Illustrated Album Pages (size 270 x 297 mm, 13-hole system) on non-ageing wood and acid-free card (170 grams) in high-resolution black and white offset print. The SF protective mounts, free of chemical softeners and with a clear non-reflecting film the same size as the pre-printed stamps, are stuck onto the album card.
These hold the stamps in place and prevent them from getting stuck. At the same time, they offer ideal protection against dust and dampness. Of course the Lighthouse illustrated album pages are also available without the SF protective mounts in the so-called "Normal" edition.
