The Profolio books are very nice but expensive. I use them to store the larger magazine ads. For anything smaller than 8 1/2 x 11" like road tests, factory photos and smaller magazine ads I go to an office supply store and buy a box of plastic sleeves that are notebook size and I find that notebooks are an inexpensive way to store and display the smaller paper collectibles. Some of the pages are compartmentalized so that you can display smaller items like business cards. Matchbook sellers offer specialized pages just for displaying the different sizes of matchbook covers or matchbooks. Small flat collectibles are easily displayed in flat glass topped boxes called Riker mounts. They are the kind of display boxes that are used to display butterflies and bugs. They work great for flat collectibles like licence plate toppers , key fobs, buttons and pins and most small collectibles. Larger collectibles like ash trays, desk sets, toys etc. just need lots of shelf space hopefully with sliding glass front doors and lights behind the frosted back panels. This collecting can get pretty serious but it is sure a lot of fun.
