Some time ago there was a discussion on this list about inexpensive,
temporary exhibition labels.  Someone said that 3M makes a black,
double-sided foam tape that peels off the walls without taking the paint
layer off with it or leaving a residue to be scraped off.  Does anyone have the
precise name of this tape?  Or are there other materials you recommend?  I
have an artist planning to exhibit a large painting made out of dozens of
small masonite squares that he wants to attach to the wall without using
nails.

Thanks for your help!
