Hi Burblespork,
Welcome to the SCF and I hope you will go and introduce yourself on the New members thread
https://goscf.com/f/11Regarding Booklets, album pages can be had for all types of Booklets,Packs and cards.
The Italian item in question and similar items would be difficult to display opened I fear ! I even had a problem for the Bicentennial USA Flag sheet until an American dealer kindly gave me a big enough album page unavailable in the UK !.
Most regular booklets can be stored opened or closed and pages are available from many companies for these. See your local dealer.
Prestige Booklets can only be stored closed without damage, unless you 'unstitch' the Booklet and display by page. I have unstitched my Old Glory Booklet and displayed each page in clear stocksheets so both sides can be viewed. This particular booklet makes for a very attractive lay-out this way.
If you open one of the pages and use a very sharp Japanese knife to carefully cut the stitching/binding, the rest of the pages will open quite easily. But be gentle.
