The stamp from Indonesia was issued in 1963. In the Geelvink Bay the
islands of Yapen (the long island nearest land) and Supiori (to the
north) are shown, but two other islands, Biak and Numfoor are missing.
The stamp with the error is not listed in the
Scott catalog, which suggests that it was withdrawn before it was
released. In any case, a stamp with the
missing islands was issued.
