1930 WC30 World Cup poster stamp with gum, original unused umm



1930 World Cup original WC30 poster stamp, with gum, original and unused UMM (unmounted mint),
issued by FIFA for officials to use on their envelopes as envelope seals and advertising material. Poster stamps were a big deal in the early days of printed fare, and a great way to distribute news, as stamps on postcards and envelopes. EXCEEDINGLY RARE to find an original still with gum, "umm" unmounted mint.
