Here’s another document that I have copied that I think is the health certificate for my great grandmother to enter the US. From my translation it’s a written certificate for Maria and Francis (the second is a guess at the name) Moretto and Catherina Negri. In the 11th Month (crossed out year) born in Locana and living in Locana.
It certifies that they have a healthy constitution, are vaccinated, and are not infected with any deadly or contagious diseases.
It looks like it is signed in Locana on November 25th, 1904- and stamped with the Locana city seal.
As the documents age they turn yellow due to the acid in the paper. There are ways to keep paper from turning yellow such as archival spray. You can also get sleeves for archiving – stores such as Gaylord Brothers are great for supplies like this. I have heard frequently about laminating documents, but DON’T.
Is it okay to laminate a document?
Lamination is not considered a safe conservation technique because the process may potentially damage a document due to high heat and pressure during application. Moreover, the laminating materials themselves may be chemically unstable and contribute even more to the deterioration of the document. Lamination also violates a cardinal rule of conservation, and that is to only apply treatments that do not alter the item and which can be reversed. Source: http://loricase.com/faq.html
All the documents I include though are with family and I have only scanned them. I would suggest to at least create a digital copy of all documents before attempting anything with them. As documents degrade over time also I have never regretted having made a digital copy (only that the technology to make a higher quality copy wasn’t available when I had the chance). I also keep a backup in a separate location.
