Self Portrait by Joseph Delaney (1904 - 1991)

Charcoal and various chalks on wove paper


The drawing was initially drawn on a wove paper that may have been the facing of a thin illustration board (acidic) and then was later mounted onto another thicker acidic mount.  Adhesive accretions were reduced from the front of the drawing where possible.  Both the thick mount and most of the illustration board were carefully reduced down to the facing paper layer using a scalpel.  The fragility of the paper and the friability of the media would not allow for further treatment so the paper was lined on the verso using Japanese paper with a remoistenable adhesive layer which needed minimal moisture to be activated.  Losses were filled with toned paper.
