Looking for ideas on how to display a collection

[Chuck Miller]

My 7yr old son is doing a cartridge collection for a Cubscout Tiger Badge requirement. For right now I'm, I mean him, will be staying away from wildcats and sticking to original chamberings. He's at about 35 pcs. right now and I'm looking for a way to label and display them. I don't want to permanently mount these, I want them to be able to remove and look at them but it has to be mobile, easily carried. Any pics of complete collections, big or small would be welcome.
