Yep, here's some pics for you.
Also, in a "previous life", I was trained to find out what was in "certain packages", just so we didn't get any "surprises"
A quick method was to spray the item with a special solvent which makes the opaque paper transparent for a short time and then vaporises and leaves no evidence (the important bit ;-)).
Unfortunately you can't get hold of the spray we used, but a fine spray of methylated spirits does a similar job.
Anyway, pics
