How to Clean Old Prints.

Ex-Libris

(1) Presuming that the injuries to your bookplates are due to age and damp, you should proceed as follows: - Place upon a flat surface a sheet of white paper somewhat larger than the print to be cleaned. Carefully dampen the print on both sides with a soft sponge, and then saturate it with a mixture of chloride of lime and oxalic acid dissolved, in about equal proportions, in a pint of cold water. You can tell when the mixture is right, by its turning magenta colour. Continue to apply it until every stain or spot has disappeared, and then with a clean sponge wash the print freely with cold water. (2) Follow the same directions for the " old engravings." If you are not handy in such matters, however, we advise you to leave the renovation to professional hands. You might write to E. Parsons & Sons, 45, Brompton Road, S.W., for an estimate.
