These scrolls are often backed to help support the weight of fragile paper. Be careful.

This is not very technical but I'm thinking the wallpaper needs to be adhered to either thin wood or heavy cardboard before hanging from a decorative drapery rod or a dowel rod with beautiful ribbon or tape.

The guy I know who is qualified to hang this hangs it archivally, over a layer of liner paper and a layer of muslin, so it can be taken down and re-installed somewhere else. Maybe backing would add protection to it hung as scrolls. Maybe you could call Zuber in NYC and they could assist you. I'm sure you know how valuable this paper is. Eldorado is one of my favorite patterns.

I think they would be best framed to protect them from edge damage and even the changes in humidity in your home . At least mounted on a materil that keesp them from the edges getting damaged .I would have them done properly like any piece of art with no glare glass and a simple black metal frame

Rare earth magnets (such as neodymium) are being used by art conservators to design installations for display for a range of objects including paper. There are a number of concerns, some mentioned above, to hanging these panels unprotected.

Unless they have a fair amount of value, I'd glue them to a fabric backing and sew a pocket in the fabric for a rod.

I would sandwich them between plexiglass held together with magnets or screws.

If originals, I would be reaching out to a museum for advice.

While sandwiching between plexi might sound promising, there are cons to this approach. Plexi has been known to bond with painted surfaces. if the surface is friable (flaking) the plexi could pull off the paint through through static charge. Plexi panels of that size are prone to bowing and will be costly (anti static plex even more $$$). Looking at the photo, the panels would need to be relaxed and flattened in order not to create permanent creases. Please consult a paper conservator who will be able to guide you to a possible solution: American Institute for Conservation https://www.culturalheritage.org/

The wallpaper was salvaged from a home (1932). See what the entire panel sold for:

Here is another link. It is still manufactured today. I would think the stamped i.d. on your panel might be of interest to them.
