I found this little gem in a big bag of miscellaneous electronic parts my mom had come across somewhere and given me.
It is a fuse with an attached disbursement ticket. If you zoom in you will notice this was issued and stamped “critical” on January 7, 1977. The bag is unopened and the fuse is in perfect condition. I’m going to go out on a limb here and say that it wasn’t THAT critical…
