Carolyn -- Check in an inconspicuous place first, but acetone squeezed out on a quickly twirled Q-tip ought to get off the white-out before liquifying it enough to merely drive it into the grain/pores of the substrate ;). Good luck! You might try a scrape-off with an x-acto blade, to see if it might just pop off, though unlikely from my experience. We use a water soluble varnish I got in the crafts area of Jo-Ann's Fabrics, intended for decoupage. I can't guarantee it's completely P.C., but IMHO it is reversible should the need arise. I use Pigma marker over it after 1/2 hr drying time. Gaylord library supply catalogue carries white permanent markers to go over dark surfaces - again suitable prepared with a water-soluble varnish. Good luck dealing with the 'good' intentions of previous conservators/ registrars! Chris Bobbitt Curator of Collections Monros Co. Historical Museum Bloomington, IN 47408 [log in to unmask]
