Hi, Well if you want to keep the original, I use a product which I buy at good ol' Home Depot for around 4$: "Natural Magic"! brand 'Odoor Absorbing Gel.' Even with my chemical sensetivities this stuff is manageble. I just close-up the container in a cardboard box with the old/musty offender for however long it takes for the unwanted SMELL to disappear. To do this,though, the object needs to be dry/beyond fungus growing (i.e. beyond feeling cold to your touch which usually indicates a low-level dampness). Yeah, and I agree that photocopying would be a good solution,too. One of my bookbinding students even photocopied early 1900's marbled endsheets to repair an old medical textbook,with passable results. If you buy an interesting paper at an art supply&cut it to match machine sizes, the photocopy shop will usually put this into their copier,too. 'good luck-from soggy Seattle(redundant!), KM
