Abstract:
A carrier and protective case are particularly useful for storing and viewing large format documents, which can be spooled together or inserted in a series of spooled transparent sleeves. The web like spools is stored on two spaced apart rollers that are in rotary engagement with opposing halves of the case, and nested within the case or a frame when the opposing halves are folded together.
