[sphere and ash]

Alan,

I highly recommend Talas (talasonline.com). You can purchase mylar presentation sleeves, pre-cut museum board backing and a storage box from them. Gaylord offers similar archival products, but I have been less pleased with their customer service. Cabinet photographs, like all photographs containing silver, are best stored away from light, humidity and wood to prevent the silver particles from oxidizing. If displayed, the photographs should be behind UV glass.
