I do the photo corners thing, and often try to add some information if what makes the item special isn't quite clear - and in my collection that's pretty common.
Here's a postcard I chanced into at the stamp show, the card is on the front of the page, and the front of it is pictured on the back along with what looks like the photo the card was made from, and another pic from a boardmember.
I print the pages on acid free cardstock, and archival clear photo corners, which are getting hard to find in stores but easy to order online. Then into page protectors - Ultra pro are nice, but in an odd twist most office supply page protectors are made from archival materials. Nicer stuff gets "nicer" pages
Just be aware that this takes up a lot more space than stacking stuff, even if the stuff is in toploaders. When I did this with some of my stamps I went from 4-5 packed pages to about 1 1/2 two inch binders.
There are pages that fit tall cards that are nice for most tickets.
