General
The drawing is black ink and graphite on thin (2), very smooth, beige (2), machine-made trace paper.

Media

• Black Ink
  This is a black, felt-tip, drawing ink that ranges from a very dark black to a middle gray.


• Green Ink Stamp
  There is an olive green ink stamp in the bottom right corner of the support. The color is somewhat variable, being slightly more brown or yellow on the right side of the stamp, and more green on the left side.


• Graphite
  There is graphite throughout, along all margins and under both kinds of black ink. There is a graphite inscription of numbers that is 37 cm from the left edge and 4.4 cm from the bottom edge of the support. There are four separate graphite lines running parallel to the edge and intersecting at the corners, on all sides.

Primary Support
Support is a thin (2), very smooth, beige (2), machine-made trace paper.

Inscriptions
There are several numerical inscriptions 37 cm from the left edge and 4.4 cm from the bottom edge of the support. There is a green ink stamp with black ink writing inside of it that reads:

General
The drawing is in good condition overall with some cockling, tears and losses at the edges, margins and corners.

Media

• Black Ink
  The black is in good condition.
• Green Ink Stamp
  The green ink stamp is in good condition.
• Graphite
  The graphite is in good condition.

Primary Support
There is a mild darkening of the rightmost third of the support.  There is a moderate level of planar distortion and cockling overall.  There is a 6.4 cm wide triangular loss in the edge of the top right corner, 4 cm from the right edge.  Part of the left edge of this triangular loss has been folded under the verso. There is a 3.4 cm wide loss in the bottom edge, 12.3 cm from the right edge.  A 6 cm long tear extends from the right edge of this loss.  There are two small, circular losses in the bottom right quadrant of the green ink stamp area.  There is a small loss in the top left margin, 16.9 cm from the left edge.  The bottom right corner is broken, and the tip is folded over onto the recto.  Creasing is present in all corners and is especially prevalent in the right half, but also extends into the body of the image area.  Due to the brittleness of the support, all edges have some amount of abrasion and small losses.  Along the right edge, there is a 1.3 cm long tear 1.4 cm from the top the loss in the bottom right corner.  There is a 5.8 cm long tear in the right edge, 12.9 cm from the bottom edge.  Along the bottom edge there is a 2.4 cm long tear, 12.9 cm from the left edge; on the same bottom edge there is also a 0.5 cm long tear, 14.2 cm from the left edge and a 1.7 cm long tear 18.9 cm from the left edge.

 

Nine (9) ambient and raking light images of the recto, including details of all four corners.

1. Tears will be mended using heat-set tissue applied on the verso, and the broken bottom right corner will be reattached with heat-set tissue.  If necessary, tears may also be mended using a very dry wheat starch paste and Japanese tissue, as exposing the support and media to any moisture could cause further cockling or migration of the black or green inks.
2. Those areas that have been folded will be locally humidified and flattened using blotters and weights, as these areas have no soluble media nearby.
3. The drawing will be housed in a Mylar folder that will then be kept in a lignin-free archival folder.  The Mylar will facilitate handling, as the support is fairly brittle and subject to further damage if kept in its current housing.

Possible Effects of Treatment

Possible Effects of Treatment
Even though all attempts will be made to avoid introducing any excess moisture to the support and media, the use of heat-set tissue may still cause distortion if the area surrounding the tear is not sufficiently flat. The Mylar folder might cause a static cling that is strong enough to cause some difficulties when removing the drawing from the Mylar. Even gentle, local humidification might cause further cockling if the paper is overly responsive.

1. Filled losses using heat-set film and Japanese tissue. 2 hours
2. Mended tears at all edges, using a combination of heat-set tissue and wheat-starch paste and Japanese tissue mends. 4 hours
3. Humidified, flattened and reattached bottom left corner. 1 hour
4. Made Mylar folder housing. 15 minutes

Total treatment time: 7.25 hours
