Restoration Process

Step 1: First we dry-clean the face and verso to remove all loose surface dirt and soiling. The original coloring will be sealed in, making sure all coloring is retained during the remainder of our work.

Step 2: Next step begins the actual cleaning process to remove stains and flaws with a procedure of de-acidification. Throughout this entire process, every attempt has been made to use nondestructive chemicals. Adina Sommer uses naturally safe methods, which are dedicated to preserving the original surface of the paper, the printing ink and the original color
