I have to separate pieces that I'm seeking advice on.
The first is a 1'x3.5' photo of the Desert Training Area in CA during WWII. The drawing has been rolled up for a very long time but does unroll and I don't think it's too dry to cause damage. That being said, there is a fair amount of dirt/residue on the photo, is there a method to clean this off? It doesn't have to perfect but I would like to preserve it the best I can. There is also a 3" tear on one end of the photo. The pieces seems to all fold back together but I don't want it to get torn further. Is there a method to fix tears or are they best left as-is?
My second problem is that someone thought it was appropriate to repair a book with masking tape, nice 2-3" masking tape... The book details the armored divisions of WW2 and was my grandfathers so I would like to display it. The problem is that in it's current state, it's not worth putting out. The tape covers the spine (with an overlap) and there are a few pieces running across the face. Is there any way to remove this tape without damaging the book? (The book has obviously started to come apart and thus why the tape was used but I'll cross that bridge once I get rid of the tape)
Thanks in advance.
If it's dirt "dirt", as in soil and dust type crud, then it will brush off with white T-shirt cotton cloth. If not, then leave it be unless you are pretty sure what it's made of. Obviously, no using of anything moist.
The tear should be stabilized on the back side of the photo. Use mending paper (anything neutral pH/non-acidic) with an organic reversible paste - put under weight for a day or so.
As for problem #2... if it were mine to do, and with the caveat that I have not seen the extent of damage in person, and if you aren't hugely worried about the monetary value of the book - then, by going really really really slowly and gently with a single-edge razor blade you can gradually remove most of the residue by scraping in a motion parallel to the surface.
I would not be afraid to lightly moisten the tape first, and then patiently work it down... being really patient.
When finished, there will be lighter dry places where you've gotten down to the support material, of course. Those can be darkened as much as they're going to be by using (believe it or not) spit. The marks won't go away 100%, but your tape and adhesive residue will be mostly gone, and it should look a lot better - aged and used for sure, but better.
Only other option is to spend $250-500 to have a paper/book conservator remove it to invisibility.
I would not increase the damage by adding any more tape or anything else, if what you want is to improve its appearance. If you are only trying to stabilize it without regard for appearance, then using binding tape is standard procedure.
Here's a link to getting preservation supplies like mending tape and neutral glue:
