In 1961 Brazil issued two stamps with a
similar design to commemorate the centenary of the issuance of the
stamps (Scott 39, 40) known as "the eye of the goat" because the image
on them reminds one of a goat's eye. On the high value there is a map
of the Netherlands, not one from 1861, but a much more recent map
in which some of the islands have been connected.
