Post-Fire Condition of the Paper/Cards:

There are tears, creases, folds, and breaks with and without attendant losses, mostly around the edges and at the corners. About 30 cards have metal fasteners/clips applied at the top edge; they are corroded and embrittled and have caused some adjacent staining, deformation, and tears/breaks in the paper. There is often delamination of the paper along the card edges. All cards have darkened and discolored, some more so than others. There is scattered staining; some of which is due to contact with water. There is heavy surface grime throughout. Many of the inks are faded. Most damages are evidence of previous use, but they are also from contact with the acidic wood container, storage in a poor environment and probable contact with water.

With the support of your donation, we would:

• Vacuum all cards individually–recto and verso–using vacuum micro attachments
• To remove more surface grime, clean each card with a foam sponge, recto and verso, especially along the top section
• Repair tears, folds, creases and breaks around edges with toned pieces of kozo-fibered Japanese tissue and wheat starch paste in order to stabilize cards for handling and to prevent further losses
• Re-adhere delaminated paper edges as necessary.
• Place small pieces of archival glassine paper, as possible, below metal clips to help protect paper below. It is probable that removing the brittle metal clips will cause more damage to the paper than leaving them in place
• As possible, remove paper label on box by introducing moisture from the front, perhaps through Gore-tex (a polytetrafluoroethylene membrane), and mechanically separating it from box
• As possible, wash label to removed discoloration and strengthen paper. Ethanol may be necessary to allow the paper to wash, test paper and ink
• Mend tears and edges with Japanese paper and wheat starch paste
• Consider lining label with Japanese paper and wheat starch paste if necessary
• Reattach label to its original position outside of box, perhaps with Japanese paper hinges and an acrylic adhesive such as Lascaux 490
• Line the inside faces of the box with a 10 point-thickness, black ragboard matboard to help buffer and protect the cards.

纸/卡火灾后的情况：

撕裂、折痕、折叠和破损，有或没有伴随的损失，主要存在边缘和角落处。大约 30 张卡片在顶部边缘应用了金属紧固件/夹子；它们被腐蚀和变脆，并导致纸张的一些相邻染色、变形和撕裂/断裂。卡片边缘的纸张通常会分层。所有的卡片都变暗变色，有些卡片比其他的更严重。有分散染色；其中一些是由于与水接触。整个表面都有很重的污垢。许多墨水都褪色了。大多数损坏是以前的使用造成的，但也可能是由于接触酸性木质容器、存放在恶劣的环境中以及可能与水接触造成的。

在您的捐款支持下，我们将：

• 将所有卡片一件件吸尘——正面和背面——使用吸尘器微型附件
• 去除更多表面污垢，使用泡沫海绵清洁每张卡片，正面和背面，尤其是顶部部分
• 修复撕裂、折叠、折痕和边缘破损，使用日本 kozo 纤维薄纸和小麦淀粉糊的调色件，以稳定卡片方便拿取并防止进一步损失
• 必要时重新粘附分层纸张边缘。
• 尽可能在金属夹下方放置小块档案玻璃纸，以帮助保护下面的纸张。与将它们留在原处相比，移除易碎的金属夹可能会对纸张造成更大的损坏。
• 尽可能通过从前面引入水分去除盒子上的纸质标签，可能是通过 Gore-tex（一种聚四氟乙烯膜），然后将其与盒子机械分离。
• 尽可能清洗标签以去除变色并加强纸张。可能需要用乙醇清洗纸张，测试纸张和墨水。
• 用日本纸和小麦淀粉糊修补撕裂和边缘。
• 如有必要，考虑用日本纸和小麦淀粉糊衬里标签
• 将标签重新贴到盒子外的原始位置，可能使用日本纸铰链和丙烯酸粘合剂，比如 Lascaux 490。
• 将盒子的内表面用 10 point 厚的黑色抹布板上一层内衬，以帮助缓冲和保护卡片。
