Several sheets that can be glued to Pringles cans or similar cylinders. They were originally made by a guy going by the handle of Tommygun on Warseer.

I print them out on full sized label sheets and just stick them to the cylinder.
An example of a modern version, suitable for Necromunda, of this can be found here.
