Jammed box

has anyone had any experience extracting a volume that is
jammed/wedged in a pull-apart box (top comes off; leather over board
with curved form at spine) -- without destroying the box (or the
book)?  it appears to have been put in the box so that the foredge
is at the spine end of the box and it is jammed in very tightly,
with little place for your fingers to grip the volume itself......
all suggestions appreciated.
