Wondering if anybody has any ideas on this, I have a piece that came in with 9 hand colored photos mounted to foam-core with a drymount film. Just wondering if there is any way to remove these without damaging the photos. It is a 9 opening mat which they would like to take out 3 photos, re-arrange and re-mat. Any ideas out there?
 
First thought: Cut the photos out complete with foam core. Lay them out on another sheet of foamcore as per desired arrangement, draw around with pencil, cut holes out and push the photos in. Secure on the back with tape.

Easier than trying to un-mount them. :D
 
Go old school, use Cut and paste.... Cut the photo and backing as a unit, and move them as a unit to the new location..... Leave extra around the edges to be covered by the new mat openings.

If you soak the prints in unseal or any other chemical solvent you could risk damage. Cutting damages the fome core not the prints attached to it. Just a thought.

That is what I was thinking of doing.
 
Another good thread. When something has old adhesive material on it, resisting the impulse to "clean" it up is a safe way to go. The old board can form a surface that can be used to secure these photos and it will probably not do much harm if it is left where it is.

Sometimes the simplest answers are just the best.

I'm doing this with Marilyn Monroe's DOD ID card issued in WWII. It was ruined because it was laminated. I cut the thing down to the edges and made a couple of slits and dunked it in a 50% solution of isopropyl alcohol, which will dissolve most adhesives given time. The plastic will separate if the adhesive is still present, which this thing did. Then it's just a matter of matching the solvent to the adhesive going weak to strongest. That part is organic chemistry involving polar and dispersion forces and the interaction of hydrogen bonding, blah, blah, blah. The isopropyl alcohol is safe and you can increase the strength until you get it right. I'm hitting it with a deacification solution now because there is a mild solvent in it. Then I may hit it with a benzene torch to see if it curls.

The deacidification solution is working. The adhesive is turning white and the plastic laminate on both sides of the ID card are beginning to separate themselves.
