Ah I should've specified. Its in Australia, the tropics, so this is definitely a humidity related problem. Ill tell her to try a dryer, see if it loosens up. Thank you! Still all ears for any other suggestions too!

Hello try to heat up with a hot dryer, it must be stuck to the pen that was still wet or you left it in a very humid place

Hi, hoping someone might have a solution for me.
My sister has an autographed photo framed, its gotten a little humidity over the last couple of years and has become a little stuck to the glass.
Anyone got an idea on how to peel it away without damaging the picture and signatures?
thanks all!
