50 WORLD ORGANIZATIONS on Stamps

Description

Whenever not all the stamps are shown it is because there were too many to fit in the scans.
I originally had several lots of these with very similar but perhaps not quite identical content. The scan is of a typical lot.
All stamp counts are approximate but are very close to exact.
NOTE: SHEETS OR BLOCKS ARE USUALLY FOLDED ALONG THE PERFORATIONS OR MAY SOMETIMES BE SEPERATED.
