A covers bargain box at NOJEX coughed-up this ZA (South African) Registered Letter Medium stamp ... the lovely 2010 Beadwork.
So what's with that bar code?
Since it was on the cover, with no other registry etiquette, I thought for a moment that it might be the registry / tracking number.
But, since there is a row of perforations between the bar code and the stamp, I began thinking that it might be an inventory control number for that individual sheet or, simpler yet, a point-of-sale bar code for that class of stamps.
Finally, the sun rose, the curtain parted, the light came on, and I thought: Why not ask for directions?
So ... waz dat bar code in the selvage?
