Map, Leo W. Schwarz Papers
(perhaps barracks at a Displaced Persons (DP) camp, 1941 August 13)
Before
Folded and brittle.
Surface dirt all over, especially on exposed side.
Print Media
Ink and pencil manuscript
Mending
While still moist, small sections were exposed for mending.
Working from the front, tears were aligned and lightly secured. Wedged gaps from expansion were realigned.
9 gsm tissue and runny Aytex-P
Bridged pieces were nipped briefly to ensure flatteningand reduce buckles
Structural mends could then be completed on back of map with heavier tissue and dryer Aytex-P.
Left under weight to fully dry.
Blotters changed as needed.
Flattening and Washing
Map was humidified with a layered, plastic humidity chamber.
Wicking occured despite precautions.
Map was washed betwween layers of spun polyester to prevent tidelines from wicking.
One deionized bath, followed by two calcium baths.
Kept humdified under gentle restaint until mending could be finished.
Unfolding
The map was gently unfolded to expose all sides.
Extensive dry cleaning with sponges to remove surface dirt.
Media testing of print and manuscript in anticipation of humidification
