I had permanent marker all over my wall once. I used the Mr. Clean Magic Eraser and it worked amazingly. There is no trace of permanent marker on my walls at all.

If the acrylic painting has been hanging for a long time, try using a cotton swab and some acetone fingernail polish remover. The polish remover should wipe the marker from the paint without lifting the paint. Take your time and use just the tip of the swab and the marker should lift off into the swab.
