Funny you should mention it Ted, because a few years ago, I found one in the b.b. of a 1960s Olmo (now in the hands of another list member). The card was indeed greasy, and it did in fact catch a lot of junk ... I even took a pic of it:
So, even the 40 year test proved OK ... guess you can go ahead and make a practice of it :)

Bike builders and mechanics have been putting paper type sleeves in the
bottom bracket housings since times prehistoric.
Even with oilers, if one didn't use them and took a bike apart once a year
to overhaul, then the grease would be fine all year unless ridden in rain or
dusty roads too long.
My dad and many others like him put a business card in the BB.
We would trim to size, smear a light coat of grease on it so it would catch
any wayward intrusion of the inner sanctum.
I've pulled bikes apart that were over 30 years old and found any number of
cards from various places in the BB's.
The card was stiff enuf to hold the contour and ID'd the bikes origen, and
if the owner's name was on it, even better.
