1944 Map of Iwo Jima
The paper support arrived in poor condition, exhibiting numerous folds, creases and tears due to extensive handling and inadequate housing. Tears and folds were previously reinforced with various pressure-sensitive tapes, which in time were likely to lead to further embrittlement of the paper.
One hard vertical crease in the center and three hard horizontal creases provided evidence of previous storage in a folded format. Additional creases and handling dents were visible throughout the sheet. Several complex tears are present at the top, center and at the top and bottom, right. Numerous smaller tears are located along the sheet edges and in weakened areas along folds. Large losses in the paper sheet were located at the top and bottom, center and left edge, above center. Smaller losses were visible within the sheet, especially in areas where folds intersect. The edges of the sheet are soft and tattered. Folded paper flaps are present at all corners and in some areas along the edges.
Pressure-sensitive tapes were used extensively to repair tears and reinforce creases both recto and verso. The tapes were applied within the printed image in some areas. Much of the tape has discolored to a golden brown color.
The paper support displays slight overall darkening; surface soiling and grime deposits are located randomly.
A facsimile of the object was produced.
The object was selectively surface cleaned with natural rubber sponge, solid white vinyl eraser, and a brush.
The carriers of pressure sensitive tapes were removed with a heated spatula. The adhesive residues from the tapes were reduced with ethanol using cotton swabs and crepe eraser.
Prior to washing, purple stamp ink and black ink signature on the verso were fixed with an ionic fixative (Cartafix WA, 25% in water). The object was washed by immersion in successive baths of calcium-enriched, deionized water.
The object was lined and paper losses were inserted with mulberry paper and wheat starch paste.
